| * ath9k: fix aggregation related interoperability issuesFelix Fietkau2011-03-14
| | | | | | | | | | | | | | | | | | | | | | Some clients seems to keep track of their reorder window even after an aggregation session has been disabled. This causes issues if there are still retried but not completed frames pending for the TID. To ensure that rx does not stall in such situations, set sendbar to 1 for any frame purged from the TID queue on teardown. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

| * ath9k: improve reliability of beacon transmission and stuck beacon handlingFelix Fietkau2011-03-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ath9k calls ath9k_hw_stoptxdma every time it sends a beacon, however there is not much point in doing that if the previous beacon and mcast traffic went out properly. On AR9380, calling that function too often can result in an increase of stuck beacons due to differences in the handling of the queue enable/disable functionality. With this patch, the queue will only be explicitly stopped if the previous data frames were not sent successfully. With the beacon code being the only remaining user of ath9k_hw_stoptxdma, this function can be simplified in order to remove the now pointless attempts at waiting for transmission completion, which would never happen at this point due to the different method of tx scheduling of the beacon queue.

| * ath9k: fix the .flush driver op implementationFelix Fietkau2011-03-14
| | | | | | | | | | | | | | | | | | This patch simplifies the flush op and reuses ath_drain_all_txq for flushing out pending frames if necessary. It also uses a global timeout of 200ms instead of the per-queue 60ms timeout. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * ath9k: fix stopping tx dma on resetFelix Fietkau2011-03-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some situations, stopping Tx DMA frequently fails, leading to messages like this: ath: Failed to stop TX DMA in 100 msec after killing last frame ath: Failed to stop TX DMA! This patch uses a few MAC features to abort DMA globally instead of iterating over all hardware queues and attempting to stop them individually. Not only is that faster and works with a shorter timeout, it also makes the process much more reliable. With this change, I can no longer trigger these messages on AR9380, and on AR9280 they become much more rare. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

| * ath9k: remove support for the FIF_PROMISC_IN_BSS filter flagFelix Fietkau2011-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware rx filter flag triggered by FIF_PROMISC_IN_BSS is overly broad and covers even frames with PHY errors. When this flag is enabled, this message shows up frequently during scanning or hardware resets: ath: Could not stop RX, we could be confusing the DMA engine when we start RX up Since promiscuous mode is usually not particularly useful, yet enabled by default by bridging (either used normally in 4-addr mode, or with hacks for various virtualization software), we should sacrifice it for better reliability during normal operation. This patch leaves it enabled if there are active monitor mode interfaces, since it's very useful for debugging.

| * mac80211: make tx() operation return voidJohannes Berg2011-02-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.
