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 PATCHv4 (all suggested by Johannes):
* change divisor to a shift when calculating 5/10 MHz bitrates or durations
to allow compiler optimization (binary shifts instead of integer divisions)
where possible
* change mandatory bitrates to accept the scan_width instead of rate flags
* typos, comments and style
As always, any comments are appreciated!
Cheers,
Simon
