2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg
This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2014-10-23ath: use CTL region from cfg80211 if unset in EEPROMFelix Fietkau
Many AP devices do not have the proper regulatory domain programmed in EEPROM. Instead they expect the software to set the appropriate region. For these devices, the country code defaults to US, and the driver uses the US CTL tables as well. On devices bought in Europe this can lead to tx power being set too high on the band edges, even if the cfg80211 regdomain is set correctly. Fix this issue by taking into account the DFS region, but only when the EEPROM regdomain is set to default. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2012-06-25ath9k: fix dynamic WEP related regressionFelix Fietkau
commit 7a532fe7131216a02c81a6c1b1f8632da1195a58 ath9k_hw: fix interpretation of the rx KeyMiss flag This commit used the rx key miss indication to detect packets that were passed from the hardware without being decrypted, however it seems that this bit is not only undefined in the static WEP case, but also for dynamically allocated WEP keys. This caused a regression when using WEP-LEAP. This patch fixes the regression by keeping track of which key indexes refer to CCMP keys and only using the key miss indication for those.

2011-12-13ath: optimize processing of CTLs for country IEs for world roaming cardsLuis R. Rodriguez
When we receive a country IE hint and we have a world roaming card we can optimize output power further by ensuring that we use the calibrated data for the country by using that country's own CTL data. That is -- when world roaming and when we process a country IE we no longer need to use the lowest output power of all CTLs instead we use an optimized CTL output power for that specific country. We accomplish this by copying the regulatory data prior on init and restoring it when cfg80211 tells us it gets a core hint. Core hints are only sent on init and when it wants to restore reguulatory settings. We take advantage of this fact and apply the cached regulatory data when we get a core hint. When we get a country IE hint though we process the regulatory data as if programmed for a specific country. Tested-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: Luis R.

2011-10-11ath9k_hw: clean up tx power handlingFelix Fietkau
The code for handling various restrictions concerning regulatory limits, antenna gain, etc. is very convoluted and duplicated across various EEPROM parsing implementations, making it hard to review.

It also removes unused transmit power scaling arrays from the EEPROM code, which belonged to an unimplemented API that isn't supposed to be in the driver anyway.
