2011-11-27ath9k: Revert change that broke AR928X on Acer Ferrari OneRafael J. Wysocki1-1/+2
Revert a hunk in drivers/net/wireless/ath/ath9k/hw.c introduced by commit 2577c6e8f232 ("ath9k_hw: Add support for AR946/8x chipsets") that caused a nasty regression to appear on my Acer Ferrari One (the box locks up entirely at random times after the wireless has been started without any way to get debug information out of it).

2011-10-11ath9k_hw: fix a regression in key miss handlingFelix Fietkau4-17/+19
The commit "ath9k_hw: Fix incorrect key_miss handling" changed the code to only report key miss errors if a MIC error wasn't reported. When checking the flags in that order in the MAC code, it might miss some real events, because the value of the MIC error flag is undefined under some conditions. The primary issue addressed by the previous commit is making sure that MIC errors are properly reported on the STA side. This can be fixed in a better way by adding a separate rx status flag for key miss and ignoring it for multicast frames. This fix slightly improves stability in AP mode on some older hardware, like AR9132. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W.

2011-10-11ath5k: remove some unneeded error handling codeDan Carpenter1-6/+0
th5k_hw_setup_tx_queue() returns a valid offset into the ah->ah_txq[] array. The ah->ah_txq[] and the ah->txqs[] array are the same size. Both have AR5K_NUM_TX_QUEUES elements. So this error handling code will never trigger. Also it's wrong. The call to ath5k_hw_release_tx_queue() with a qnum of AR5K_NUM_TX_QUEUES or more will just trigger a WARN_ON() and return. Or if it missed the WARN_ON(), it would just corrupt some memory and return.

2011-10-03ath9k_hw: set pci_express capability true for AR9480Mohammed Shafi Shajakhan1-1/+6
the AR_SREV register does not seems to indicate whether AR9480 is pci_express capable or not though the other information like macVersion etc can be obtained properly. this fix is essential as ASPM won't be intialized and its related driver functionality ath9k_hw_configpcipowersave won't be called Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.

2011-10-03ath9k_hw: Fix number of GPIO pins for AR9287/9300Mohammed Shafi Shajakhan1-0/+4
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 Cc: stable@kernel.org Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.
