* ath9k: add a better fix for the rx tasklet vs rx flush raceFelix Fietkau2013-01-11
| | | | | | | | | | | Ensure that the rx tasklet is no longer running when entering the reset path. Also remove the distinction between flush and no-flush frame processing. If a frame has been received and ACKed by the hardware, the stack needs to see it, so that the BA receive window does not go out of sync.

* ath9k: Remove 'stations' debugfs fileSujith Manoharan2012-11-21
| | | | | | | | | | | | | The 'stations' debugfs file has multiple issues. It doesn't scale to an arbitrary number of associated stations and allocating 64K is not elegant either. Now that changes have been made in mac80211 to support dynamic creation/deletion of driver-specific debugfs files on station addition/removal, remove this file and make use of the mac80211 hooks (which will be done in a sebsequent patch).

* ath9k: Fix the 'xmit' debugfs fileSujith Manoharan2012-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | The 'xmit' debugfs file has become big and unwieldy, fix multiple issues with its usage: * Store TX counters/statistics only for the 4 Access Categories. Use IEEE80211_NUM_ACS instead of ATH9K_NUM_TX_QUEUES. * Move various utility macros to debug.h, they can be reused elsewhere. * Remove tx_complete_poll_work_seen. * Remove code that accesses various internal queue-specific variables without any locking whatsoever. HW/SW queue details will be handled in a subsequent patch. * Do not print internal values like txq_headidx and txq_headidx. They were mostly unused anyway, considering code like: PRX("txq_tailidx: ", txq_headidx); * Handle 'txprocdesc' for EDMA too.

* ath9k: Fix MCI reset in BT cal_reqRajkumar Manoharan2012-11-21
| | | | | | | | | | | This patch reverts the commit "ath9k_hw: Wait BT calibration to complete" and bail out from MCI interrupt routine for chip reset. The above commit stalls the WLAN TCP traffic while bringing up and down the BT interface iteratively. Fixing this properly by queueing up chip reset and bailing out properly from tasklet routine.

| * ath9k: make PA linearization optional, disabled by default and fix checksFelix Fietkau2012-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | Some checks for PA linearization support checked ATH9K_HW_CAP_PAPRD and some used the EEPROM ops, leading to issues in tx power handling, since those two can be out of sync.
