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.

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.

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.

2011-07-13ath9k_hw: Fix incorrect key_miss handlingSenthil Balasubramanian
Decryping frames on key_miss handling shouldn't be done for Michael MIC failed frames as h/w would have already decrypted such frames successfully anyway. Also leaving CRC and PHY error(where the frame is going to be dropped anyway), we are left to prcoess Decrypt error for which s/w decrypt is selected anway and so having key_miss as a separate check doesn't serve anything. So making key_miss handling mutually exlusive with other RX status handling makes much more sense. This patch addresses an issue with STA not reporting MIC failure events resulting in STA being disconnected immediately.

2011-07-11ath9k_hw: fix MAC clock rate for AR9287 v1.3+Felix Fietkau
This chip uses the async FIFO feature and runs the MAC at 117 MHz Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-07-11ath9k_hw: fix MAC clock for half/quarter rateFelix Fietkau
Enabling half/quarter rate makes the MAC run at half/quarter clock speed. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-07-11ath9k_hw: always enable 5 GHz fast clock for AR9280Felix Fietkau
All devices support this, but some disable it using an EEPROM flag for some reason. Improves 5 GHz performance on those devices. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-07-11ath9k_hw: remove hardcoded PLL overrides for AR9280Felix Fietkau
Use the proper masks for the register instead. Fixes adding the (still unused) half/quarter PLL flags. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
