* ath9k_htc: Fix BSSID calculationSujith Manoharan2011-05-191-0/+1
| | | | | | | | | | The BSSID/AID has to be set for the first associated station interface. Subsequent interfaces may move out of assoc/disassoc status, in which case, the BSSID has to be re-calculated from the available interfaces. Also, ANI should be enabled or disabled based on the current opmode. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath9k_htc: Add a timer to cleanup WMI eventsSujith Manoharan2011-04-131-1/+7
| | | | | | | | | | | Occasionally, a WMI event would arrive ahead of the TX URB completion handler. Discarding these events would exhaust the available TX slots, so handle them by running a timer cleaning up such events. Also, timeout packets for which TX completion events have not arrived.

* ath9k_htc: Drain packets on station removalSujith Manoharan2011-04-131-0/+1
| | | | | | | | | | When a station entry is removed, there could still be pending packets destined for that station in the HIF layer. Sending these to the target is not necessary, so drain them in the driver itself. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k_htc: Drain pending TX frames properlySujith Manoharan2011-04-131-2/+4
| | | | | | | | | | | | | | | | | When doing a channel set or a reset operation the pending frames queued up for transmission have to be flushed and sent to mac80211. Fixing this has to be done in two separate steps: * Flush queued frames and kill the URB TX completion handler. * Complete all the frames that in the TX pending queue. This patch adds proper support for draining and all the callsites namely, channel change/reset/idle/stop are fixed. A separate queue is used for handling failed frames.

* ath9k_htc: Add TX slotsSujith Manoharan2011-04-131-1/+4
| | | | | | | | | | Maintain a bitmap of slots for transmission and update the cookie field for every packet with the slot value. This value would be used for matching packets when TX completion processing is added. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k_htc: Move endpoint header parsing to TX taskletSujith Manoharan2011-04-131-0/+1
| | | | | | | | | There is no need to do endpoint header removal in the ISR. Also, this is needed when TX slot management is added later on. Use a helper function to strip the driver header.

* ath9k_htc: Introduce new HTC APISujith Manoharan2011-04-131-0/+1
| | | | | | | | | | | | | | A new routine that takes an endpoint explicitly is introduced. The normal htc_send() now retrieves the endpoint from the packet's private data. This would be useful in TX completion when the endpoint ID would be required. While at it, use a helper function to map the queue to endpoint. Data/mgmt/beacon packets use htc_send(), while WMI comamnds pass the endpoint to HTC. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k_htc: Fix TX queue managementSujith Manoharan2011-04-131-3/+10
| | | | | | | | | | | Handle queue start/stop properly by maintaining a counter to check if the pending frame count has exceeded the threshold. Otherwise, packets would be dropped needlessly. While at it, use a simple flag to track queue status and use helper functions too. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W.

* ath9k_htc: Use SKB's private area for TX parametersSujith Manoharan2011-04-131-1/+13
| | | | | | | | | | | | | | For all packets sent through the USB_WLAN_TX_PIPE endpoint, the private area of the SKB's tx_info can be used to store driver-specific information. For packets sent through USB_REG_OUT_PIPE, this will not make a difference since they are routed through a separate routine that doesn't access the private region. This would help in situations where TX information is required in the URB callback. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W.

* ath9k_htc: Queue WMI eventsSujith Manoharan2011-04-131-1/+2
| | | | | | | | | | | | Use a queue to handle WMI events and schedule a tasklet to process the events. This fixes the race between the WMI event ISR and the SWBA tasklet when the arrival of WMI events in quick succession could overwrite the SWBA data before the tasklet from a previous iteration could have been scheduled. Also, drain the WMI queue properly. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k_htc: Fix beacon miss under heavy loadSujith Manoharan2011-04-131-0/+7
| | | | | | | | | | | | Transmission of beacons becomes erratic when TX load is high, since the latency involved in the generation of a SWBA interrupt on the target to the actual sending of a beacon is quite high for USB devices. Fix this by adjusting the beacon response time. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath9k_htc: Add TSF adjust capabilitySujith Manoharan2011-04-131-0/+3
| | | | | | | | | | In multi-interface mode, beacons/probe responses that are sent out must have their timestamp field updated.

| | | | | | | | | | | | | | | | mac80211 stores the association state in ieee80211_bss_conf. Use this and remove the local state, which is incorrect anyway since it is stored globally and not on a per-VIF basis. Restarting ANI and reconfiguration of HW beacon timers when a scan run ends requires more work. This is handled by iterating over the active interfaces.
