The patch titled
TI acx1xxx wireless driver
has been removed from the -mm tree. Its filename was
acx1xx-wireless-driver.patch
This patch was dropped because workqueue changes broke it and I doubt if anyone is using it anyway

Oh no. Yes. I forgot to remove some standalone build aids.

acx-update 2
EDESC
[20051016] 0.3.13
* Revert 20051013 fix, we have one which actually works.
Thanks Jacek Jablonski <yacek87@xxxxxxxxx> for testing!
[20051013]
* trying to fix "yet another similar bug"
* usb fix by Carlos Martin
[20051012] 0.3.12
* acx_l_clean_tx_desc bug fixed - was stopping tx completely
at high load. (It seems there exists yet another similar bug!)
* "unknown IE" dump was 2 bytes too short - fixed
* DUP logging made less noisy
* another usb fix by Carlos Martin <carlosmn@xxxxxxxxx>
[20051003]
* several usb fixes by Carlos Martin <carlosmn@xxxxxxxxx> - thanks!
* unknown IE logging made less noisy
* few unknown IEs added to the growing collection
* version bump to 0.3.11
[20050916]
* fix bogus MTU handling, add ability to change MTU
* fix WLAN_DATA_MAXLEN: 2312 -> 2304
* version bump to 0.3.10
[20050915]
* by popular request default mode is 'managed'
* empty handler for EID 7 (country info) is added
* fix 'timer not started - iface is not up'
* tx[host]desc micro optimizations
* version bump to 0.3.9
[20050914]
* tx[host]desc ring workings brought a bit back to two-hostdesc
scheme. This is an attempt to fix weird WG311v2 bug.
I still fail to understand how same chip with same fw can
work for me but do not work for a WG311v2 owner. Mystery.
* README updated
* version bump to 0.3.8
[20050913]
* variable and fields with awful names renamed
* a few fields dropped (they had constant values)
* small optimization to acx_l_clean_tx_desc()
* version bump to 0.3.7
[20050912]
* stop using 16 byte "private area" in txdesc - fw bug makes it unreliable
* better logging of DUPs
* version bump to 0.3.6
[20050911]
* use alloc_netdev/free_netdev/netdev_priv
* acx_inline.h incorporated into pci.c
* helper.c + helper2.c = common.c
* marking static functions
* enable IE_DOT11_CURRENT_ANTENNA for acx111
* version bump to 0.3.5

Update drivers/net/wireless/tiacx driver from version 0.3.14 to 0.3.23.
[20051228]
* Global s/acxlog/log/
[20051220] 0.3.23

* acx_s_update_card_settings cosmetic change
(but wasn't run tested)
[20051201] 0.3.21
* Thanks Carlos Martin
* Completely serialize USB rx. Tiny speed loss,
but even more safe wrt reordering.
* A few msleeps removed
[20051128] 0.3.20
* we will use only 2 rx usb buffers now. No apparent speed loss,
eliminates usb packet reordering risk.
* two USB fixes for real bugs and one fix for possible leak
of an urb on error path. Thanks Carlos Martin <carlosmn@xxxxxxxxx>.
[20051116] 0.3.19
* a few small fixes accumulated over time, nothing spectacular
[20051031] 0.3.18
* hopefully a final touch on USB tx autorate
[20051022] 0.3.17
* PCI command submission made simpler
[20051021] 0.3.16
* Small changes mostly designed to break USB ;)
* Auto rate handling for USB is still not confirmed to work.
I need USB logs from the users.

tiacx-fix-attribute-packed-warnings fix
EDESC
The patch tiacx-fix-attribute-packed-warnings.patch takes care of many of
the 'packed attribute' warnings, but I noticed that some of these warnings like:
drivers/net/wireless/tiacx/wlan_compat.h:246: warning: 'packed' attribute ignored for field of type 'u8[5u]'
drivers/net/wireless/tiacx/wlan_hdr.h:476: warning: 'packed' attribute ignored for field of type 'wlanitem_u32_t'
drivers/net/wireless/tiacx/wlan_mgmt.h:253: warning: 'packed' attribute ignored for field of type 'u8'
are still present for the i386/allmodconfig build on gcc-4.1.1 for 2.6.18-mm1.
So I made a patch for the files where it is still a problem. This compiled
without warnings.

+ - switch fw cmd length structs depending on whether acx100 or acx111
+ - fix log message rate limiting (as a benefit code is now faster, too)
+ - unify acx100/acx111 scanning, saving a couple hundred bytes
+ - set Ctl2_8 to 0 which it most likely should be (please report if
+ this breaks anything - but it shouldn't since it's being initialized
+ to 0 on driver init anyway...)

+[20060104] 0.3.24
+* From Andreas Mohr <andim2@xxxxxxxxxxxxxxxxxxxxx>
+ - activated acx100 configoption readout, unified acx100/acx111 parsing
+ - init NULL data template, required for 802.11 power save mode
+ - return actual, valid txpower levels in range ioctl (from configoption!)
+ fix bugs:
+ - fatal bug in 802.11 powersave structs
+ - some missing endianness conversions
+ - check for sane regulatory domain related settings on both SETting and GETting
+ - random optimizations making this much enhanced code *smaller* than the
+ previous version!
+ - optimized struct layout
+ - merge acx100_s_init_packet_templates and acx111_s_init_packet_templates
+ - use kzalloc instead of kmalloc where useful (yes, this driver is Linux 2.6.x
+ only, with x rather large)
+ - avoid some sprintf() and strlen()
+ - add support for new get_wireless_stats handling (...silence deprecation
+ warning!)
+ - add some unlikely()
+ - lower msleep() value in issue_cmd() in order to speed up card initialization
+ time (almost less than 1 second now, on P3/700!). should this lower msleep()
+ value be made init-only??
+ - disable get sensitivity ioctl for USB (unfortunately not working yet)
+ - make sure to call synchronize_irq(), (semi-)required for SMP
+ - group together some closely related functions
+ - misc cleanups/code maintenance
+ So, configoptions are now working for acx100, too, and unified, and
+ 802.11 power save mode actually worked for acx100 when I tested it (large
+ delays during ping which indicate that it must be active, but I guess these
+ delays should be much reduced with a properly tuned implementation), but it's
+ not finished and thus not enabled by default.

+* Thanks Carlos Martin
+* Completely serialize USB rx. Tiny speed loss,
+ but even more safe wrt reordering.
+* A few msleeps removed
+
+[20051128] 0.3.20
+* we will use only 2 rx usb buffers now. No apparent speed loss,
+ eliminates usb packet reordering risk.
+* two USB fixes for real bugs and one fix for possible leak
+ of an urb on error path. Thanks Carlos Martin <carlosmn@xxxxxxxxx>.
+
+[20051116] 0.3.19
+* a few small fixes accumulated over time, nothing spectacular
+
+[20051031] 0.3.18
+* hopefully a final touch on USB tx autorate
+
+[20051022] 0.3.17
+* PCI command submission made simpler
+
+[20051021] 0.3.16
+* Small changes mostly designed to break USB ;)
+* Auto rate handling for USB is still not confirmed to work.
+ I need USB logs from the users.
+
+[20051020] 0.3.15
+* Auto rate handling for USB is implemented. Untested.
+
+[20051019]
+* first step in proper auto rate handling for USB
+
+[20051018] 0.3.14
+* update for 2.6.14-rc4-mm1
+* Kconfig bug (error if ACX=y, ACX_USB=y, USB=m) fixed
+* PARANOID_LOCKING off by default
+
+[20051016] 0.3.13
+* Revert 20051013 fix, we have one which actually works.
+ Thanks Jacek Jablonski <yacek87@xxxxxxxxx> for testing!
+
+[20051013]
+* trying to fix "yet another similar bug"
+* usb fix by Carlos Martin
+
+[20051012] 0.3.12
+* acx_l_clean_tx_desc bug fixed - was stopping tx completely
+ at high load. (It seems there exists yet another similar bug!)
+* "unknown IE" dump was 2 bytes too short - fixed
+* DUP logging made less noisy
+* another usb fix by Carlos Martin <carlosmn@xxxxxxxxx>
+
+[20051003]
+* several usb fixes by Carlos Martin <carlosmn@xxxxxxxxx> - thanks!
+* unknown IE logging made less noisy
+* few unknown IEs added to the growing collection
+* version bump to 0.3.11
+
+[20050916]
+* fix bogus MTU handling, add ability to change MTU
+* fix WLAN_DATA_MAXLEN: 2312 -> 2304
+* version bump to 0.3.10
+
+[20050915]
+* by popular request default mode is 'managed'
+* empty handler for EID 7 (country info) is added
+* fix 'timer not started - iface is not up'
+* tx[host]desc micro optimizations
+* version bump to 0.3.9
+
+[20050914]
+* tx[host]desc ring workings brought a bit back to two-hostdesc
+ scheme. This is an attempt to fix weird WG311v2 bug.
+ I still fail to understand how same chip with same fw can
+ work for me but do not work for a WG311v2 owner. Mystery.
+* README updated
+* version bump to 0.3.8
+
+[20050913]
+* variable and fields with awful names renamed
+* a few fields dropped (they had constant values)
+* small optimization to acx_l_clean_tx_desc()
+* version bump to 0.3.7
+
+[20050912]
+* stop using 16 byte "private area" in txdesc - fw bug makes it unreliable
+* better logging of DUPs
+* version bump to 0.3.6
+
+[20050911]
+* use alloc_netdev/free_netdev/netdev_priv
+* acx_inline.h incorporated into pci.c
+* helper.c + helper2.c = common.c
+* marking static functions
+* enable IE_DOT11_CURRENT_ANTENNA for acx111
+* version bump to 0.3.5
+
+[20050910]
+* minor fixes, 2.6.13-mm2 integration
+
+[20050905]
+* TIWLAN_DC is dead, ui32ACX[TR]xQueueStart is dead
+* massive mucking with PCI and USB resulting in:
+ acx_pci.o + acx_usb.o = acx.o ;)
+ Why? Here's why:
+ text data bss dec hex filename
+ 116199 452 40 116691 1c7d3 acx.o
+ 103435 244 20 103699 19513 acx_pci.o
+ 81732 196 32 81960 14028 acx_usb.o
+* helper.c is PCI/USB independent now. It was the last one.
+* both modular and non-modular builds, PCI, USB, PCI+USB,
+ seem to compile successfully!
+* version bump to 0.3.4
+
+[20050904]
+* acx_stop_queue() locking reviewed and mostly fixed
+* 2.4isms in USB code are officially dead
+* added debug stuff for discovering interrogate/configure IEs
+* version bump to 0.3.3
+
+[20050903]
+* locking bug on error path fixed
+* issue_cmd() logging made more sane
+* issue_cmd() callers may abstain from printing issue_cmd() errors:
+ issue_cmd() itself gives enough info
+* version bump to 0.3.2
+
+[20050902]
+* kill bogus configure() call in acx100_s_create_dma_regions()
+
+[20050901]
+* acx100_s_create_dma_regions: hopefully fixed for USB
+ (problem found with help of Carlos Martin <carlosmn@xxxxxxxxx> - thanks!)
+* a load of cleanups:
+* acx_s_create_tx_desc_queue -> acx_create_tx_desc_queue
+ (it doesn't sleep)
+* struct acxp80211_nullframe -> acx_template_nullframe
+* xXBUFFERCOUNT_ACXnn -> xXBUFCNT_ACXnn
+* xXBUFFERCOUNT_USB -> USB_xXBUFCNT: these are _unrelated_ to xXBUFCNT_ACXnn,
+ should have visibly different names
+* TODOs added (we have a few really Pascalish/Windowish names,
+ and some misleading ones)
+* version bump to 0.3.1
+
+[20050830]
+* finally kill warning about acx_s_activate_power_save_mode()
+* struct acx100_ie_memconfigoption: convert pRxHostDesc to acx_ptr type
+* massive move of device-independent code from helper.c to helper2.c
+
+[20050829]
+* dummy handler for NONERP EID (47) added
+
+[20050823]
+* driver submitted for kernel inclusion
+* #defines renamed: CONFIG_ACX_{PCI,USB} -> ACX_{PCI,USB}
+ (needed for correct compilation of two modules from the same source)
+* version bump to 0.3.0
+* sizes:
+ text data bss dec hex filename
+ 78242 264 8 78514 132b2 drivers/net/wireless/acx/acx_pci.o
+ 60622 208 20 60850 edb2 drivers/net/wireless/acx/acx_usb.o
+
+[20050822]
+* idma.c is incorporated into helper.c
+* lots of cosmetic work: comments, struct member shuffling,
+ etc. TIWLAN_DC and other PCI data structs are #ifdef'ed
+ to be PCI-only. A few todos added. Extra #include's removed.
+* added sem locking debug printout code (for amd64 debug)
+* beacon tx rate and beacon ratevector is updated according to
+ "iwconfig rate" command immediately (required mode change before).
+
+[20050821]
+* Switch to wrapper functions for dealing with "tx buffers"
+ (memory areas where we create packets for tx. For USB, it's just
+ a part of wlandevice_t, for PCI it's a DMAable buffer pointed to
+ by txhostdesc).
+* Completely hide nature of PCI txdescs under opaque pointer type tx_t*
+* acx_l_ether_to_txdesc -> acx_l_ether_to_txbuf, not using knowledge
+ of PCI txdesc anymore.
+* Massive surgery on usb.c, cutting all paths into PCI code.
+* PCI code moved to pci.c - USB don't need these pieces anymore
+* acx111 and acx100 txhostdesc creation unified into single function
+
+[20050816]
+* PCI code switched to single-txdesc scheme
+* version bump to 0.2.5
+
+[20050815]
+* dev_kfree_skb -> dev_kfree_skb_any
+
+[20050814]
+* Auto rate was reset to lowest rate by scanning code
+ (AP beacons did it every tenth of a second!). Fixed.
+* USB rx no longer uses PCI-style rx descriptor ring.
+ tx ring elimination needs 'single-descriptor' setup
+ to be developed for acx100 (patch exists for acx111).
+* Very strange sem locking problems are reported on amd64.
+ Code which misbehaves looks fine. I do not know what's going on.
+ Workaround: turn off preemption.
+
+[20050812]
+* acx100 was failing to find out radio module #,
+ and wanted to load radio module 00. Must be fixed now.
+* USB: more simplifications
+
+[20050810]
+* USB: simplified command submission code, removed some
+ wlandevice_t fields (now unused)
+
+[20050808]
+* USB changes: nuked global statics, simplified issue_cmd,
+ shortened wlandevice_t. Added some TODOs :)
+
+[20050807]
+* restart scan if AP is not found
+* remove use_eth_name parameter. It was deprecated
+* disable legacy firmware loader for 2.6. Driver printed a warning
+ about need to switch to hotplug.
+* WARNING: new names for firmware images!
+ Driver will try to load the following images:
+ PCI driver:
+ 'tiacxNNNcMM' (NNN=100/111, MM=radio module ID (in uppercase hex)):
+ combined firmware for specified chipset and radio.
+ failing that, it will try to load images named
+ 'tiacxNNN' (NNN=100/111): main firmware for specified chipset
+ and 'tiacxNNNrMM': corresponding radio module.
+ For example, my firmware is in file named 'tiacx111c16'.
+ Alternatively, I may remove it and use pair of files
+ 'tiacx111' and 'tiacx111r16' instead.
+ USB driver: loads image named 'tiacx100usb'
+ Hint: you can keep both old and new image names (via symlinks
+ or just by copying files) if you need to run older driver.
+* fix "Debug: sleeping function called from invalid context..." for USB
+* ACX_{PCI,USB} -> CONFIG_ACX_{PCI,USB} in preparation to 2.6 merge
+* version bump to 0.2.4
+
+[20050804]
+* 'Fixed' deadlock on flush_scheduled_work (need a better fix eventually)
+* We didn't completely disable IRQs on ifdown -> "Disabling IRQ#NN"
+ on second modprobe. Fixed.
+
+[20050802]
+* removed some // comments in order to please Andreas
+* moved a field to PCI-only part of wlandevice_t
+* Random Version Bump (tm) to 0.2.3
+* no code changes
+
+[20050730]
+* Basically just incorporating acx-20050722.acx100fixed.patch
+ This is a bit of a backward step, because instead of figuring out
+ why active scanning doesn't work for acx100, we just disable it.
+ acx100 owners encouraged to try to make it work
+
+[20050729]
+* Added some IE IDs
+
+[20050726]
+* added probe request config to acx100_s_init_packet_templates,
+ maybe acx100 is working now
+
+[20050721]
+* del_timer_sync() sem lockup on SMP maybe fixed
+
+[20050720]
+* lots of amd64 warnings fixed, thanks to Matan Peled <chaosite@xxxxxxxxx>
+
+[20050710]
+* {tx,rx}hostdesc->desc_phy removed (was not used)
+* netdev->type of ARPHRD_IEEE80211_PRISM was sticking forever
+ after monitor mode. Fixed
+* monitor mode tx is working again
+* rate reporting added in monitor mode packet header
+
+[20050709]
+* moved PCI specific ioctls to pci.c
+* ioctl.c is PCI/USB independent now
+
+[20050708]
+* Fixed one apparent bug (wlandevice_t had different
+ layout for PCI and USB - conv.c would die horribly)
+* Massive code shuffling with only trivial code changes.
+ Mostly sorting out PCI/USB stuff into relevant files.
+* ihw.c eliminated
+* helper2.c is PCI/USB independent now

+** LOGGING
+**
+** - Avoid SHOUTING needlessly. Avoid excessive verbosity.
+** Gradually remove messages which are old debugging aids.
+**
+** - Use printk() for messages which are to be always logged.
+** Supply either 'acx:' or '<devname>:' prefix so that user
+** can figure out who's speaking among other kernel chatter.
+** acx: is for general issues (e.g. "acx: no firmware image!")
+** while <devname>: is related to a particular device
+** (think about multi-card setup). Double check that message
+** is not confusing to the average user.
+**
+** - use printk KERN_xxx level only if message is not a WARNING
+** but is INFO, ERR etc.
+**
+** - Use printk_ratelimited() for messages which may flood
+** (e.g. "rx DUP pkt!").
+**
+** - Use log() for messages which may be omitted (and they
+** _will_ be omitted in non-debug builds). Note that
+** message levels may be disabled at compile-time selectively,
+** thus select them wisely. Example: L_DEBUG is the lowest
+** (most likely to be compiled out) -> use for less important stuff.
+**
+** - Do not print important stuff with log(), or else people
+** will never build non-debug driver.

+** LOCKING
+** We have adev->sem and adev->lock.
+**
+** We employ following naming convention in order to get locking right:
+**
+** acx_e_xxxx - external entry points called from process context.
+** It is okay to sleep. adev->sem is to be taken on entry.
+** acx_i_xxxx - external entry points possibly called from atomic context.
+** Sleeping is not allowed (and thus down(sem) is not legal!)
+** acx_s_xxxx - potentially sleeping functions. Do not ever call under lock!
+** acx_l_xxxx - functions which expect lock to be already taken.
+** rest - non-sleeping functions which do not require locking
+** but may be run under lock
+**
+** A small number of local helpers do not have acx_[eisl]_ prefix.
+** They are always close to caller and are to be revieved locally.
+**
+** Theory of operation:
+**
+** All process-context entry points (_e_ functions) take sem
+** immediately. IRQ handler and other 'atomic-context' entry points
+** (_i_ functions) take lock immediately on entry, but dont take sem
+** because that might sleep.
+**
+** Thus *all* code is either protected by sem or lock, or both.
+**
+** Code which must not run concurrently with IRQ takes lock.
+** Such code is marked with _l_.
+**
+** This results in the following rules of thumb useful in code review:
+**
+** + If a function calls _s_ fn, it must be an _s_ itself.
+** + You can call _l_ fn only (a) from another _l_ fn
+** or (b) from _s_, _e_ or _i_ fn by taking lock, calling _l_,
+** and dropping lock.
+** + All IRQ code runs under lock.
+** + Any _s_ fn is running under sem.
+** + Code under sem can race only with IRQ code.
+** + Code under sem+lock cannot race with anything.

+* acx_l_transmit_reassocresp
+
+You may be wondering, just like me, what the hell ReAuth is.
+In practice it was seen sent by STA when STA feels like losing connection.
+
+[802.11]
+
+5.4.2.3 Reassociation
+
+Association is sufficient for no-transition message delivery between
+IEEE 802.11 stations. Additional functionality is needed to support
+BSS-transition mobility. The additional required functionality
+is provided by the reassociation service. Reassociation is a DSS.
+The reassociation service is invoked to 'move' a current association
+from one AP to another. This keeps the DS informed of the current
+mapping between AP and STA as the station moves from BSS to BSS within
+an ESS. Reassociation also enables changing association attributes
+of an established association while the STA remains associated with
+the same AP. Reassociation is always initiated by the mobile STA.
+
+5.4.3.1 Authentication
+...
+A STA may be authenticated with many other STAs at any given instant.
+
+5.4.3.1.1 Preauthentication
+
+Because the authentication process could be time-consuming (depending
+on the authentication protocol in use), the authentication service can
+be invoked independently of the association service. Preauthentication
+is typically done by a STA while it is already associated with an AP
+(with which it previously authenticated). IEEE 802.11 does not require
+that STAs preauthenticate with APs. However, authentication is required
+before an association can be established. If the authentication is left
+until reassociation time, this may impact the speed with which a STA can
+reassociate between APs, limiting BSS-transition mobility performance.
+The use of preauthentication takes the authentication service overhead
+out of the time-critical reassociation process.
+
+5.7.3 Reassociation
+
+For a STA to reassociate, the reassociation service causes the following
+message to occur:
+
+ Reassociation request
+
+* Message type: Management
+* Message subtype: Reassociation request
+* Information items:
+ - IEEE address of the STA
+ - IEEE address of the AP with which the STA will reassociate
+ - IEEE address of the AP with which the STA is currently associated
+ - ESSID
+* Direction of message: From STA to 'new' AP
+
+The address of the current AP is included for efficiency. The inclusion
+of the current AP address facilitates MAC reassociation to be independent
+of the DS implementation.
+
+ Reassociation response
+* Message type: Management
+* Message subtype: Reassociation response
+* Information items:
+ - Result of the requested reassociation. (success/failure)
+ - If the reassociation is successful, the response shall include the AID.
+* Direction of message: From AP to STA
+
+7.2.3.6 Reassociation Request frame format
+
+The frame body of a management frame of subtype Reassociation Request
+contains the information shown in Table 9.
+
+Table 9 Reassociation Request frame body

+ Q - DQPSK (Differential Quaternary Phase Shift Keying)
+ C - CCK (Complementary Code Keying, a form of DSSS
+ (Direct Sequence Spread Spectrum) modulation)
+ O - OFDM (Orthogonal Frequency Division Multiplexing)
+Optional:
+ o - OFDM
+ d - CCK-OFDM (also known as DSSS-OFDM)
+ p - PBCC (Packet Binary Convolutional Coding)
+
+The term CCK-OFDM may be used interchangeably with DSSS-OFDM
+(the IEEE 802.11g-2003 standard uses the latter terminology).
+In the CCK-OFDM, the PLCP header of the frame uses the CCK form of DSSS,
+while the PLCP payload (the MAC frame) is modulated using OFDM.
+
+Basically, you must use CCK-OFDM if you have mixed 11b/11g environment,
+or else (pure OFDM) 11b equipment may not realize that AP
+is sending a packet and start sending its own one.
+Sadly, looks like acx111 does not support CCK-OFDM, only pure OFDM.
+
+Re PBCC: avoid using it. It makes sense only if you have
+TI "11b+" hardware. You _must_ use PBCC in order to reach 22Mbps on it.
+
+Preambles:
+
+Long preamble (at 1Mbit rate, takes 144 us):
+ 16 bytes ones
+ 2 bytes 0xF3A0 (lsb sent first)
+PLCP header follows (at 1Mbit also):
+ 1 byte Signal: speed, in 0.1Mbit units, except for:
+ 33Mbit: 33 (instead of 330 - doesn't fit in octet)
+ all CCK-OFDM rates: 30
+ 1 byte Service
+ 0,1,4: reserved
+ 2: 1=locked clock
+ 3: 1=PBCC
+ 5: Length Extension (PBCC 22,33Mbit (11g only)) <-
+ 6: Length Extension (PBCC 22,33Mbit (11g only)) <- BLACK MAGIC HERE
+ 7: Length Extension <-
+ 2 bytes Length (time needed to tx this frame)
+ a) 5.5 Mbit/s CCK
+ Length = octets*8/5.5, rounded up to integer
+ b) 11 Mbit/s CCK
+ Length = octets*8/11, rounded up to integer
+ Service bit 7:
+ 0 = rounding took less than 8/11
+ 1 = rounding took more than or equal to 8/11
+ c) 5.5 Mbit/s PBCC
+ Length = (octets+1)*8/5.5, rounded up to integer
+ d) 11 Mbit/s PBCC
+ Length = (octets+1)*8/11, rounded up to integer
+ Service bit 7:
+ 0 = rounding took less than 8/11
+ 1 = rounding took more than or equal to 8/11
+ e) 22 Mbit/s PBCC
+ Length = (octets+1)*8/22, rounded up to integer
+ Service bits 6,7:
+ 00 = rounding took less than 8/22ths
+ 01 = rounding took 8/22...15/22ths
+ 10 = rounding took 16/22ths or more.
+ f) 33 Mbit/s PBCC
+ Length = (octets+1)*8/33, rounded up to integer
+ Service bits 5,6,7:
+ 000 rounding took less than 8/33
+ 001 rounding took 8/33...15/33
+ 010 rounding took 16/33...23/33
+ 011 rounding took 24/33...31/33
+ 100 rounding took 32/33 or more
+ 2 bytes CRC
+
+PSDU follows (up to 2346 bytes at selected rate)
+
+While Signal value alone is not enough to determine rate and modulation,
+Signal+Service is always sufficient.
+
+Short preamble (at 1Mbit rate, takes 72 us):
+ 7 bytes zeroes
+ 2 bytes 0x05CF (lsb sent first)
+PLCP header follows *at 2Mbit/s*. Format is the same as in long preamble.
+PSDU follows (up to 2346 bytes at selected rate)
+
+OFDM preamble is completely different, uses OFDM
+modulation from the start and thus easily identifiable.
+Not shown here.
