* ath: unshare struct ath_bus_ops between ath5k and ath9kFelix Fietkau2011-04-143-8/+15
| | | | | | | | | This struct is not used in any common code, and moving it out of the ath header makes it easier to add more driver specific ops. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Tested-by: Sedat Dilek <sedat.dilek@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | Request a re-configuration of Beacon related timers on the receipt of the first Beacon frame has to be set only for station mode. Setting beacon sync for IBSS is causing wrong beacon slot selection on beacon generation. Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.

* ath9k: avoid using trinary operator w/ TX_STAT_INCJohn W. Linville2011-04-141-1/+4

* ath9k_htc: Use separate URB pool for management framesSujith Manoharan2011-04-132-9/+108
| | | | | | | | | | | | Beacon transmission needs to involve as little latency as possible after receiving a SWBA event from the target. Since packets are buffered to use TX stream mode, beacon frames sometimes gets queued up and are not sent out immediately. Fix this by decoupling management frame transmission from the normal data path and send them out immediately. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W.

| | | | | | | | | | | 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 Manoharan2011-04-136-0/+54
| | | | | | | | | | When a station entry is removed, there could still be pending packets destined for that station in the HIF layer.

* ath9k_htc: Optimize HTC start/stop APISujith Manoharan2011-04-133-21/+6

* ath9k_htc: Drain pending TX frames properlySujith Manoharan2011-04-136-49/+69
| | | | | | | | | | | | | | | | | 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: Introduce new HTC APISujith Manoharan2011-04-136-30/+49
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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.
