This patchset adds support for 5 and 10 MHz in nl80211/cfg80211/mac80211
and enables support in ath5k and ath9k, which already support this feature
on the driver side. 5 and 10 MHz wide channels might be useful for:
* long shot links, as the transmissions are more robust
* future support for 802.11y which allows some 5 and 10 MHz channels in
3.6 GHz range
* future support for 802.11p which uses 10 MHz in 5.9 GHz range
* ... and more "special" applications.
This patchset enables 5 and 10 MHz channels only for OFDM, and without
HT/MIMO/aggregation (for now). Support may be added later.
Changes to PATCHv3:
* some patches dropped which were already merged by Johannes
* add new patches:
* nl80211: add scan width to bss and scan request
* mac80211/rc80211: add chandef to rate initialization
* cfg80211/mac80211: get mandatory rates based on rate flags
* mac80211: allow scanning for 5/10 MHz channels in IBSS
* mac80211: return if IBSS chandef can not be used
* add scan/bss handling support for 5/10 MHz (see new patches above)
* add chandef parameter to rate control API (see new patches above)
* never access hw.conf to acquire the current channel width/chandef
-> this should (in theory?) make this usable in chanctx drivers as well
* fix txpower according to Felix' suggestion
* various smaller fixes
As always, any comments are appreciated!
Cheers,
Simon
