And make use of it in b43. This fixes a regression introduced with 49d55cef5b1925a5c1efb6aaddaa40fc7c693335 b43: N-PHY: implement spurious tone avoidance This commit made BCM4322 use only MCS 0 on channel 13, which of course resulted in performance drop (down to 0.7Mb/s).

2013-03-27b43: N-PHY: use more bits for offset in RSSI calibrationRafał Miłecki1-2/+2
When calculating "offset" for final RSSI calibration we're using numbers bigger than s8 can hold. We have for example: offset[j] = 232 - poll_results[j]; formula. If poll_results[j] is small enough (it usually is) we treat number's bit as a sign bit. For example 232 - 1 becomes: 0xE8 - 0x1 = 0xE7, which is not 231 but -25. This code was introduced in e0c9a0219a8f542e3946fe972a68aacf8c3f906c and caused stability regression on some cards, for ex. BCM4322.

2013-03-27b43: N-PHY: increase initial value of "mind" in RSSI calibrationRafał Miłecki1-2/+2
We're using "mind" variable to find the VCM that got the best polling results. For each VCM we calculte "currd" which is compared to the "mind". For PHY rev3+ "currd" gets values around 14k-40k. Looking for a value smaller than 40 makes no sense, so increase the initial value. This fixes a regression introduced in 3.4 by commit: e0c9a0219a8f542e3946fe972a68aacf8c3f906c (my BCM4322 performance dropped from 18,4Mb/s to 9,26Mb/s) Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: John W.

Drivers that don't use chanctxes cannot perform VHT association because they still use a "backward compatibility" pair of {ieee80211_channel, nl80211_channel_type} in ieee80211_conf and ieee80211_local.
