2012-07-10ath9k_hw: remove debugging masks from AR_MCI_INTERRUPT_RX_MSG_DEFAULTRajkumar Manoharan1-6/+0
Remove the CONT_* and LNA_* messages from AR_MCI_INTERRUPT_RX_MSG_DEFAULT. Those MCI rx messages only meant for debugging purpose. Including them in default rx_msg series could raise huge amount of MCI interrupts when BT traffic is going on. And also it increases power consumption when WLAN is scanning.

2012-07-09ath9k: Stop the BTCOEX timers before disabling BTCOEXMohammed Shafi Shajakhan2-2/+2
Its safe to stop the BTCOEX timers 'period_timer' and 'no_stomp_timer' before disabling BTCOEX. These timers can call ath9k_hw_btcoex_enable (or) change the BT stomp type if they seem to be running after we had called ath9k_hw_btcoex_disable, which is obviously not correct.

2012-07-09ath9k: Fix MCI cleanupMohammed Shafi Shajakhan1-1/+3
We are doing MCI cleanup eventhough BTCOEX is not enabled via module parameter. This means we do ath_mci_cleanup though we skipped calling ath_mci_setup. Yet it does not causes any issues now as we free the DMA buffer allocated only when it is allocated during ath_mci_setup.

2012-07-09ath9k_hw: fix AR9462 2g5g switch on full resetRajkumar Manoharan1-12/+6
On full reset, mci reset will put LNA update on 2G mode. And Whenever 2g5g_switch is forced at the end of full reset, lna update should not be skipped. Not doing so, is affecting WLAN rx and causing beacon loss when BTCOEX is enabled on AR9462. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

As soon as the interface brought up, btcoex timer starts running eventhough the interface is in idle state and WLAN chip is moved to full sleep mode. There is no point in running btcoex timer when the wlan interface is in sleep mode and also it might consumes more power on WLAN idle unassociated state. So lets stop the btcoex when wlan is idle state. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-07-09ath9k_hw: do not load noise floor readings when it is runningRajkumar Manoharan1-8/+5
Noise floor calibration is performed on longcal interval and the reading will be updated in history buffer. On rare occasions, the previous noisefloor calibration might not be completed within the period and trying to load nf reading will be failed. In such situation, postpone the nf cabliration to next cycle to give enough time to complete the calibration. This was already taken care for ar9002 chips.

2012-06-28ath9k: fix ANI operation in AP modeFelix Fietkau2-15/+15
ath9k_ani_reset (which is called at reset time) uses a state variable ani->update_ani to prevent the ANI noise immunity state on the operating channel from being overwritten by background scans. Unfortunately this is also being set for AP mode, since it's mixed with code that is only supposed to change the default settings after a reset. In AP mode this has the side effect of having ANI run, but being unable to change its runtime noise immunity level, making it effectively useless. Fix this by getting rid of ani->update_ani and passing a parameter to ath9k_hw_set_ofdm_nil and ath9k_hw_set_cck_nil instead.

mac80211 adds stations in HT IBSS as soon as a frame comes by, even if the HT capabilities are not known yet (they are often received later, e.g. in beacons). So far, ampdu factor/density are only calculated when the station is initially added. This patch changes this to update ampdu factor/density settings when starting a blockack session.

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.
