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 PATCHv2:
* instead of introducing new bitrate tables, use bitrate flags which mark
the bitrate with support for 5/10 MHz. All bitrates have then to be
calculated manually.
--> this saves a few changes where we only operate on indexes anyway,
but requires some more checking at other parts where it is required
to see if the rate is supported in 5/10 MHz. At least it is not
that ugly and bloaty, and also saves a lot of code in drivers.
* various DIV_ROUND_UP()s have been used instead of manual conversions
--> this was squashed with the "big" bitrate adjustment patch (-1 patch)
* found a bug in the rate mask matching code, which is fixed (+1 patch)
* fixed a few bugs I introuced myself. :)
As always, any comments are appreciated!
Cheers,
Simon
