2009-03-27mac80211: unify and fix TX aggregation startJohannes Berg
When TX aggregation becomes operational, we do a number of steps: 1) print a debug message 2) wake the virtual queue 3) notify the driver Unfortunately, 1) and 3) are only done if the driver is first to reply to the aggregation request, it is, however, possible that the remote station replies before the driver! Thus, unify the code for this and call the new function ieee80211_agg_tx_operational in both places where TX aggregation can become operational. Additionally, rename the driver notification from IEEE80211_AMPDU_TX_RESUME to IEEE80211_AMPDU_TX_OPERATIONAL. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2009-03-27ath9k: Fix rate control update for aggregated framesVasanthakumar Thiagarajan
We will miss rate control update if first A-MPDU of an aggregation is not Block Acked as we always tell if the rate control needs to updated through update_rc of first A-MPDU. This patch does rate control update for the first A-MPDU which notifies it's tx status (which is not necessarily the first A-MPDU of an aggregation) to mac80211.

2009-03-27ath9k: Fix bug in handling single stream stationsSujith
AP mode currently sets up the dual stream capability for all stations. This patch fixes it by checking if the associated station supports dual stream MCS rates (8-15). We would disregard any MCS rates above 15, since Atheros HW supports only 0..15 rates currently, and can't receive at rates > 15 anyway.

2009-03-27ath9k: remove dummy PCI "retry timeout" fixLuis R. Rodriguez
Remove the PCI retry timeout code as that was just taken from ipw2100 due to historical reasons but in reality its a no-op, additionally its simply incorrect as each PCI devices has its own custom PCI configuration space on PCI config space >= 0x40. Not to mention we were trying to write 0 to a place that already has 0 on it.

2009-03-05ath9k: Add a debugfs interface for controlling virtual wiphysJouni Malinen
debugfs ath9k/phy#/wiphy can be used to show the current list of virtual wiphys and to add/remove virtual wiphys. Eventually, this interface could be replaced with a cfg80211/nl80211 command that is passed through mac80211. For example: # cat /debug/ath9k/phy0/wiphy primary: phy0 # echo add > /debug/ath9k/phy0/wiphy # cat /debug/ath9k/phy0/wiphy primary: phy0 secondary: phy1 # echo del=phy1 > /debug/ath9k/phy0/wiphy # cat /debug/ath9k/phy0/wiphy primary: phy0 In addition, following commands can be used to test pausing and unpausing of the virtual wiphys: pause=phy1 unpause=phy1 select=phy1 (select pauses and unpauses wiphys automatically based on channel) schedule=500 (set wiphy scheduling interval in msec; 0 = disable; default value: 500) Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.

2009-03-05ath9k: Add a simple virtual wiphy schedulerJouni Malinen
This is a very simple scheduler that goes through the wiphys and schedules one at a time every N milliseconds (current default value: 500 ms).

Allow mac80211-controlled channel changes on an active wiphy and especially during a scan. We need this as long as the scan is controlled by mac80211.
