* ath6kl: Move and rename ath6kl_cleanup_vif functionMohammed Shafi Shajakhan2012-11-271-33/+1
| | | | | | | | | | | | Rename ath6kl_cleanup_vif function as 'ath6kl_cfg80211_vif_stop' which is the more appropriate name considering the functionality of the module and vif specific cleanup is actually done by ath6kl_cfg80211_vif_cleanup. Also move it to cfg80211.c. Also make ath6kl_cfg80211_sta_bmiss_enhance as static function. This addresses a FIXME/TODO.

| | | | | | | | | | | WLAN_ENABLED is vif specific, not part of the driver's struct ath6kl. Proper clearing of this flag is already taken care in ath6kl_cleanup_vif.

| | | | | | | | | | | | AR6004(UB134) firmware supports only LP Endpoint, So map all Access Categories to Low Priority endpoints. This fixes a WPA2 connection issue as the uplink(tx) endpoint is appropriately mapped in sync with the firmware.

* ath6kl: Fix inactivity timeout for AR6004Mohammed Shafi Shajakhan2012-10-241-5/+8
| | | | | | | | | | | | | | Currently AR6004 handles the inactivity timeout resolution in minutes rather than seconds. So parse the inactivity timeout to the firmware in minutes. For now we will cleanup the inactive station entries to the nearest converted minutes (ex: an inactive time of 70 seconds would take atleast 2 - 3 minutes) Tested with surprise removal of client cards/host shutdown.

* ath6kl: Fix reconnection issue after recoveryVasanthakumar Thiagarajan2012-10-241-1/+5
| | | | | | | | | | | | | Disallowing any wmi commands while re-initializing the firmware results in connection failures after recovery is done in open/WEP mode. To fix this, clear WMI_READY, to make sure no wmi command is tried while fw is down. Remove ATH6KL_STATE_RECOVERY state check in ath6kl_control_tx() so that any configuration during fw init time will go through using wmi commands.

* ath6kl: Add support to detect fw error through heart beatVasanthakumar Thiagarajan2012-10-241-6/+0
| | | | | | | | | | | | | | | | | | This patch adds support to detect fw error condition by sending periodic message (heart beat challenge) to firmware. Upon reception of the message, fw would send a response event to driver. When there are no reponses from fw for about 5 cmd driver would trigger the recovery logic assuming that fw has gone into an error state. Capable fw will advertise this capability through ATH6KL_FW_CAPABILITY_HEART_BEAT_POLL bit. This feature is disabled by default, can be enabled through a modparam (heart_beat_poll). This modparam also confiures the polling interval in msecs. Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

* ath6kl: rework scheduled scanThomas Pedersen2012-10-241-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | This patch reflects changes in the firmware scheduled scan implementation to behave better in cases with multiple concurrent vifs. Major changes: - scheduled scan filters and state are now programmed per-vif. - decouple scheduled scan from host sleep. To maintain graceful failure with old firmwares, a new firmware capability bit is introduced: ATH6KL_FW_CAPABILITY_SCHED_SCAN_V2. ath6kl simply won't advertise scheduled scan to cfg80211 if the SCHED_SCAN_V2 is not supported. Since firmwares from here on out won't support the previous implicit API for scheduled scan (set WoW filters and host sleep), bump the firmware API to protect old drivers. Unfortunately, due to firmware RAM constraints ath6kl still cannot expect a scan complete event at the end of a scheduled scan results cycle, so the sched_scan_timer is retained.
