* ath9k: use new FIF_PSPOLL configure filterLuis R. Rodriguez2009-08-14
| | | | | | | | | | | | We used to set pspoll filter on ath9k on AP mode but we no longer need this mode specific check as mac80211 now does the check for us and informs us when we should enable pspoll through FIF_PSPOLL.

* | ath9k: call ath9k_hw_detach() once upon hw init failureLuis R. Rodriguez2009-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If hw initialization fails (ath9k_hw_init()) on ath_init_softc() we bail out and call ath9k_hw_detach(). The call ath9k_hw_detach() is conditional though as ath9k_hw_init() could itself have called ath9k_hw_detach(). Just describing this is itself a brain twister. Avoid this nonsense by removing ath9k_hw_detach() from ath9k_hw_init(). Upon hw initialization failure we expect the callers to take care of the cleanup. Signed-off-by: Luis R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mac80211 workqueue exists to enable mac80211 and drivers to queue their own work on a single threaded workqueue. mac80211 takes care to flush the workqueue during suspend but we never really had requirements on drivers for how they should use the workqueue in consideration for suspend. We extend mac80211 to document how the mac80211 workqueue should be used, how it should not be used and finally move raw access to the workqueue to mac80211 only. Drivers and mac80211 use helpers to queue work onto the mac80211 workqueue: * ieee80211_queue_work() * ieee80211_queue_delayed_work() These helpers will now warn if mac80211 already completed its suspend cycle and someone is trying to queue work. mac80211 flushes the mac80211 workqueue prior to suspend a few times, but we haven't taken the care to ensure drivers won't add more work after suspend. To help with this we add a warning when someone tries to add work and mac80211 already completed the suspend cycle. Drivers should ensure they cancel any work or delayed work in the mac80211 stop() callback. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

* | ath5k: update PCU opmode whenever a new interface is addedBob Copeland2009-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we would store the operating mode at interface up time, but only update the PCU registers when the next reset happened. The result is that if beacon configuration (ops->bss_info_changed) happens before ops->config, we will program the wrong things into the timer registers. Consequently, beacons won't work in AP mode until after a reset (channel change, scan etc.). This is fragile anyway so just program the opmode as soon as mac80211 gives it to us.

To improve the range, make 6.5Mbps as the lowest rate in 11na ht40 mode, this improves the range by approximately 2dB. 11ng ht40 does not have this issue as it also has basic rates (1, 2, 5.5 and 11).
