2011-11-11ath9k_hw: Fix regression of register offset for AR9003 chipsRajkumar Manoharan
commit 52d6d4ef5e6d1517688e27c11c01ab303ec681dd upstream. My recent commits (3782c69d, 324c74a) introduced regression for register offset selection that based on the macversion. Not using parentheses in proper manner for ternary operator leads to select wrong offset for the registers. This issue was observed with AR9462 chip that immediate disconnect after the association with the following message ieee80211 phy3: wlan0: Failed to send nullfunc to AP 00:23:69:12:ea:47 after 500ms, disconnecting.

2011-11-11ath9k: disable unnecessary PHY error reportingFelix Fietkau
commit ac06697c79bad09e44a8b1d52104014016fb90de upstream. PHY errors relevant for ANI are always tracked by hardware counters, the bits that allow them to pass through the rx filter are independent of that. Enabling PHY errors in the rx filter often creates lots of useless DMA traffic and might be responsible for some of the rx dma stop failure warnings.

commit 6321eb0977b011ac61dfca36e7c69b2c4325b104 upstream. this patch fixes the assumption of maximum number of GPIO pins present in AR9287/AR9300. this fix is essential as we might encounter some functionality issues involved in accessing the status of GPIO pins which are all incorrectly assumed to be not within the range of max_num_gpio of AR9300/AR9287 chipsets Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.

2011-11-11ath9k_hw: Fix magnitude/phase coeff correctionRajkumar Manoharan
commit e9c10469cf3c71bc1c6b0f01319161e277d6ac9b upstream. Do the magnitude/phase coeff correction only if the outlier is detected. Updating wrong magnitude/phase coeff factor impacts not only tx gain setting but also leads to poor performance in congested networks. In the clear environment the impact is very minimal because the outlier happens very rarely according to the past experiment. It occured less than once every 1000 calibrations.

2011-08-22ath9k_hw: Fix STA (AR9485) bringup issue due to incorrect MAC addressSenthil Balasubramanian
Due to some recent optimization done in the way the mac address bytes are written into the OTP memory, some AR9485 chipsets were forced to use the first byte from the eeprom template and the remaining bytes are read from OTP. AR9485 happens to use generic eeprom template which has 0x1 as the first byte causes issues in bringing up the card. So fixed the eeprom template accordingly to address the issue.

This cleans up error handling for the beacon in case of dma mapping failure. We need to free the skb when dma mapping fails instead of nulling and leaking the pointer, and we should bail out to avoid giving the hardware the bad descriptor. Finally, we need to perform the null check after trying to update the beacon, or else beacons will never be sent after a single mapping failure.

2011-07-18carl9170: set beacon xmit power to the maxChristian Lamparter
Harshal Chhaya discovered during network tests, that several of his clients dropped-off the network. The captured packets shows that the beacons sent by the AP are at a much lower power than the other data packets. The reason for this mishap: The driver never updated the beacon phy register, so all beacons were always sent at the lowest power.

2011-07-15ath9k: improve reliability of MIC error detectionFelix Fietkau
For unicast the hardware sometimes reports MIC errors even though the frame that it received actually contains a valid MIC - on some chips this can happen frequently enough to trigger TKIP countermeasures. Fix this issue by not reporting MIC errors for unicast frames with a valid key, letting mac80211 validate the MIC instead. Additionally, strip the MIC for all frames that the hardware considers valid to avoid wasting CPU cycles re-validating it. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2011-07-13ath5k: disable 32KHz sleep clock operation by defaultFelix Fietkau
While 32 KHz sleep clock might provide some power saving benefits, it is also a major source of stability issues, on OpenWrt it produced some reproducible data bus errors on register accesses on several different MIPS platforms. All the Atheros drivers that I can find do not enable this feature, so it makes sense to leave it disabled in ath5k as well.

During scans the full calibration usually does not make much sense, PAPD probing and IQ calibration should be deferred until there is enough time to complete them. Adding 100 ms to the initial full calibration delay should be enough to do this. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Acked-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.
