2015-02-03ath9k: Check early for multi-vif/STA conditionsSujith Manoharan1-15/+7
If multiple interfaces are active or there is no associated station interface, bail out early and return 1 so that mac80211 can proceed with the normal suspend routine. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-02-03ath9k: Remove redundant device_can_wakeup() checkSujith Manoharan1-6/+0
WOW capability is registered with mac80211 only when the device has the ability to wakeup, so there is no need to check in the suspend() routine. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2015-01-29ath10k: fix target wakeup timeoutRajkumar Manoharan1-1/+1
During drv_start/drv_stop stress testing in ARM platform, sometimes target is taking more that 5ms to wake up. Similar behaviour also noted during driver load and unload iterations. On such cases, the wakup duration lies between 5-6ms. Hence increasing pci wakup timeout 10ms to be more safer. With this changes, able to complete power down/up >100 iterations without any issues.

2015-01-29ath10k: disable sta keepaliveMichal Kazior2-0/+47
Firmware revisions providing sta keepalive service have it enabled by default. mac80211 already does idle connection polling so it makes no sense to duplicate this in ath10k. mac80211 wouldn't even know of the offloaded keepalive NullFunc frames.

On some AR955x/QCA953x boards, noise floor calibration gets stuck and the cause is a hardware/BB issue. To fix this, peak detect calibration in the HW is disabled and is done in the driver instead.

Tuning rings size for performance optimization. Increasing Tx ring size, allows buffering more packets for HW, thus eliminating idle periods which were observed with smaller ring at high throughput, because HW was fetching packets faster than driver was filling them into the TX ring.
