cfg80211_sme_scan_done() can be called (by fullmac cards) with wdev->conn == NULL when CFG80211_SME_CONNECTING. We quit silently instead of WARN_ON in this case. Signed-off-by:

cfg80211 now guarantees keys are set after connecting. We can remove the key cache code from the driver now. Signed-off-by:

We used to return the result of wait_event_interruptible_timeout() which is the remaining timeout on success. But this information is not used by any of its callers. So we just return 0 on success. This fixed a erroneous return value bug for iwm_set_key(). Signed-off-by:

The recent cfg80211 "rework key operation" patch from Johannes Berg makes sure keys are set only after the connection has been established. So we can remove the setting WEP keys before essid support from the driver. Signed-off-by:

We were treating ieee80211_regdom module parameter hints as core hints, this means we were not letting the user help compliance further when using the module parameter. It also meant that users with a device with a custom regulatory domain set (wiphy->custom_regulatory) using this module parameter were being stuck to the original default core static regualtory domain. We fix this by using the static cfg80211_regdomain alpha2 as the core hint and treating the module parameter separately. All iwlwifi and ath5k/ath9k/ar9170 devices which world roam set the wiphy->custom_regulatory. This change allows users using this module parameter to have it trated as a a proper user hint and not have it ignored. Signed-off-by:

This uses the new configuration changes indicated up by mac80211 when all interfaces are marked idle. We need to do a little more work as we have our own set of virtual wiphys within ath9k. Only when all virtual wiphys are inactive do we allow an idle state change for a wiphy to trigger disabling the radio. Signed-off-by:

These functions are changing the power mode of the chip, but this may have unpredictable effects, if another code are trying to set the power mode via 'ath9k_hw_setpower' in the same time from another context. Changes-licensed-under: ISC Signed-off-by:

The hardware doesn't generate interrupts in some cases and so work around this by monitoring the TX status periodically and reset the chip if required. This behavior of the hardware not generating the TX interrupts can be noticed through ath9k debugfs interrupt statistics when heavy traffic is being sent from STA to AP. One can easily see this behavior when the STA is transmitting at a higher rates. The interrupt statistics in the debugfs interface clearly shows that only RX interrupts alone being generated and TX being stuck. TX should be monitored through a timer and reset the chip only when frames are queued to the hardware but TX interrupts are not generated for the same even after one second. Also, we shouldn't remove holding descriptor from AC queue if it happens to be the only descriptor and schedule TX aggregation regarless of queue depth as it improves scheduling of AMPDUs from software to hardware queue.

Running iperf along with p2p traffic on both TX and RX side then stop one side, then stop the other side, then start it up again, eventually the STA gets into a mode that it can not pass data at all. A hardware workaround for invalid RSSI can make FIFO write pointer to jump over read pointer, causing RX data corruption and repeated DMA. Both TX and RX works fine when the workaround is disabled. To replace the original hardware work around, software looks for frames with post delimiter CRC error and mark the RSSI invalid so that the upperlayer will not use the RSSI associated with this frame. So disable the hardware workaround by updating the appropriate registers. Signed-off-by:

RSSI reported by the RX descriptor requires little manipulation. Manipulate and report the correct RSSI to the stack. This will fix the improper signal levels reported by iwconfig iw dev wlanX station dump. Also the Link Quality reported seems to be varying (falls to zero also sometimes) when iperf is run from STA to AP. Also use the default noise floor for now as the one reported during the caliberation seems to be wrong.

All current rate control algorithms agree to send management and no-ack frames at the lowest rate. They also agree to do this when sta and the private rate control data is NULL. We add a hlper to mac80211 for this and simplify the rate control algorithm code. Developers wishing to make enhancements to rate control algorithms are for broadcast/multicast can opt to not use this in their gate_rate() mac80211 callback. Cc: Zhu Yi <yi.zhu@intel.com> Acked-by:
