2012-06-25ath9k: fix dynamic WEP related regressionFelix Fietkau1-0/+1
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.

2011-12-14ath: optimize processing of CTLs for country IEs for world roaming cardsLuis R. Rodriguez1-0/+1
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.

AR9462 chips have the capabilities to provoide bluetooth profile information. For non-AR9462 btcoex chips, the BT priority traffic was identified by periodically polling the respective registers and updated dutycycle, stomptype, etc. As AR9462 chip offers the BT profile informations, let us make use of that to update aggregation limit, dutycycle, stomptype and wieghtages.

2011-10-12ath9k_hw: clean up tx power handlingFelix Fietkau1-1/+0
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. This patch partially cleans up the mess by unifying regulatory limit handling in one function and simplifying handling of antenna gain. 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.

ath.ko is a common module shared between ath5k, ar9170usb, ath9k and ath9k_htc. Adding driver specific data to the shared structure would impact all the drivers. Handling USB device recognition for devices specific to ath9k_htc can be handled within the driver itself. Also, AR7010 refers to the processor used in both AR9280/AR9287 based devices. Rename the device enumerations accordingly. While at it, check properly for the bus type when choosing the EEPROM base address for UB95.

2010-12-08ath: Add and use ath_printk and ath_<level>Joe Perches1-0/+103
Add ath_printk and ath_<level> similar to dev_printk and dev_<level> from device.h This allows a more gradual rename of ath_print to to ath_dbg or perhaps ath_debug. This basically removes debug.h leaving only an #define ath_printk ath_dbg there and moving all the ATH_DBG_<foo> enums to ath.h I do not think there's much purpose for struct ath_common * being passed to the ath_printk functions, but perhaps there might be.
