2011-04-19ath9k: assign keycache slots to unencrypted stationsFelix Fietkau
Frame filtering relies on having a valid destination index (keycache slot), to keep track of the destination. Assigning a keycache slot (configured to unencrypted, with no key data attached) improves powersave handling in AP mode with no encryption. The dummy keycache entry for a station is cleared, when a real key gets added. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-04-19ath9k: fix powersave frame filtering/buffering in AP modeFelix Fietkau
This patch fixes a long standing issue of pending packets in the queue being sent (and retransmitted many times) to sleeping stations. This was made worse by aggregation through driver-internal retransmitting of A-MDPU subframes. Previously the hardware tx filter was cleared unconditionally for every single packet - with this patch it uses the IEEE80211_TX_CTL_CLEAR_PS_FILT for unaggregated frames. A sta_notify driver op is added to stop aggregation for stations when they enter powersave mode. Subframes stay buffered inside the driver, to ensure that the BlockAck window keeps a sane state. Since the driver uses software aggregation, the clearing of the tx filter needs to be handled by the driver instead of mac80211 for aggregated frames.

2011-04-19ath9k: Fix beacon generation on foreign channelRajkumar Manoharan
While leaving the oper channel, beacon generation is stopped by mac80211 and beacon slots are marked as inactive. During the scan, ath9k configures beacon timers based on IEEE80211_CONF_OFFCHANNEL which inturn generates beacon alert even though bslot is inactive. ath9k fails to disable beacon alert while moving to offchannel if none of the beacon slot is active. This is causing beacon transmission on foreign channel. This patch enables swba based on active bslots. This issue was reported with two vifs (AP+STA) and triggered scan in STA vif in unassociated state. Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.

2011-04-19ath: fix 0x6C for beaconing/passive scan flags based on country IELuis R. Rodriguez
The 0x6C regulatory domain is just like the 0x6A regulatory domain but differs in that 0x6C will allow adhoc and active scan on its channels only if we are associated to an AP with a country IE that allows those channels. The ath_reg_apply_beaconing_flags() does just this -- we respect the manufacturer's intent on only enabling beaconing modes of operation if and only if blessed by the country IE.

2011-04-19ath9k: fix the return value of ath_stoprecvFelix Fietkau
The patch 'ath9k_hw: fix stopping rx DMA during resets' added code to detect a condition where rx DMA was stopped, but the MAC failed to enter the idle state. This condition requires a hardware reset, however the return value of ath_stoprecv was 'true' in that case, which allowed it to skip the reset when issuing a fast channel change.

2011-04-14ath5k: disable 5 GHz support for the dualband PHY chip on dual-radio AR5312Felix Fietkau
There are two variants of AR5312 dual-band devices, one single-radio and the other one dual-radio. On the dual-radio board, the first MAC only supports 5 GHz, even though it has a dual-band PHY. The 2.4 GHz part of this phy is used in pass-through mode, connecting the second MAC with the second PHY. Disable 2.4 GHz for the first MAC on an AR5312, but only if the board configuration indicates a dual-radio device.

2011-04-13ath9k_htc: Use separate URB pool for management framesSujith Manoharan
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.

2011-04-13ath9k_htc: Drain pending TX frames properlySujith Manoharan
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.
