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 PATCHv1: * the actual datarates are handled, not the corresponding 20MHz rates as before. This should make it compatible to freebsd, although I was informed that some other implementors might still use the corresponding 20MHz rates. Anyway, from looking at the standard using the actual rates should be the right thing to do. * txpower is decremented according to channel bandwidth (the regulation I checked all define limits in dBm/MHz) * radiotap support for 5/10 MHz channel flag was added * some fixes for ath5k/ath9k were included to make them interoperable (having the same SIFS improved performance quite well, 300kbps -> 6600 kbps for 5 MHz channels :) ) As always, any comments are appreciated!
