In case of firmware event, driver need to release resources for the station but not send another disconnect WMI command. In case of upper layer request, WMI_DISCONNECT_STA_CMDID command need to be issued for the firmware to perform disconnect on the MAC layer. Eventually, event is expected to confirm MAC disconnect, but it is better to not wait for firmware event and release station resources immediately. FW may fail to report disconnect for various reasons, so one could not rely on event always reported. Introduce parameter to distinguish 2 cases above to prevent double WMI command issuing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "goto chip_reset" is a bit misleading, because it does not actually issue a chip reset. Instead it is bypassing processing of other interrupts and assumes that the tasklet will issue a chip reset. In the case of RXORN this does not happen, so bypassing processing of other interrupts will simply allow them to fire again. Even if RXORN was triggering a reset, it is not critical enough to need the bypass here. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

At this point, the queued up packets might be processed if some other operation schedules the sdata work. Since the tids have been cleaned up already, warnings are hit. If this doesn't happen, the packets are left in the queue until the interface is torn down. Since initiating a BA session when scan is in progress leads to flaky connections, especially in MCC mode, we can drop the TX BA request. This improves connectivity with legacy clients in MCC mode.

* | | | ath9k: Improve flush() in mcc modeSujith Manoharan2014-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flush timeout in MCC mode is very small, since we are constrained by the time slice for each channel context, but since only the HW queues are flushed when switching contexts, it is acceptable. Since the SW queues are also emptied in the mac80211 flush() callback, a larger duration is needed. Add an override argument to __ath9k_flush() and set it when flush() is called in MCC mode.

In MCC mode, since the offchannel/RoC timer is set with the requested duration, ieee80211_remain_on_channel_expired() needs to be called when the timer expires. But, currently it is done after we move back to the operating channel. This is incorrect - fix this by calling ieee80211_remain_on_channel_expired() when the RoC timer expires and in ath_roc_complete() when the RoC request is aborted.

In MCC mode, we need to check the HW queues alone, since the SW queues are just marked as 'stopped' - they will be processed in the next context switch. But since we don't differentiate this now, mention whether we want to check if there are frames in the SW queues. * The flush() callback checks both HW and SW queues. * The tx_frames_pending() callback does the same. * The call to __ath9k_flush() in MCC mode checks HW queues alone.
