2019-03-07mt76: mt76x02: only update the base mac address if necessaryFelix Fietkau
Also update the mask first before calculating the vif index. Fixes an issue where adding back the same interfaces in a different order fails because of duplicate vif index use Fixes: 06662264ce2ad ("mt76x02: use mask for vifs") Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-02-26mt76: mt76x02: only reset beacon drift counter when enabling beaconsFelix Fietkau
When the timer is already running, there is no need to reset the counter, because the drift will remain the same. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-26mt76: mt76x02: fix beacon timer issueFelix Fietkau
When mt76x0 and mt76x2 beacon code was unified, it changed the order in which beacon enable and beacon interval are configured. Configuring beacon enable before beacon interval can in some cases cause problems with the beacon timer, leading to clients not waking up properly from powersave mode. Fix this by changing the order back to interval first, then enable.

Port mt76x02_check_tx_hang watchdog from vendor driver in order to perform a device reset when tx mac/dma logic hangs. Tx mac/dma stuck has been observed when the device is heavy loaded or in a noisy environment. Moreover introduce wdt delayed work in order to run tx_hang watchdog.

2018-11-30mt76: fix race condition in station removalFelix Fietkau
If there are still pending packets in the tx queue when removing a station, it could possibly lead to a call to further attempts to pull packets from the mac80211 tx queue after it has already been removed from the scheduling list. Prevent this from happening by calling synchronize_rcu after deleting the wcid pointer before further cleaning up the tx queues. To be extra careful, ensure that mtxq->list is always initialized properly. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2018-11-30mt76: avoid queue/status spinlocks while passing tx status to mac80211Felix Fietkau
There is some code in the mac80211 tx status processing code that could potentially call back into the tx codepath. To avoid deadlocks, make sure that no tx related spinlocks are taken during the ieee80211_tx_status call. Signed-off-by: Felix Fietkau <nbd@nbd.name>

2018-11-30mt76x02: assure we update gain after scanStanislaw Gruszka
Assure that after we initialize dev->cal.low_gain to -1 this will cause update gain calibration. Otherwise this might or might not happen depending on value of second bit of low_gain and values read from registers in mt76x02_phy_adjust_vga_gain().

2018-11-30mt76x02: run calibration after scanningStanislaw Gruszka
If we are associated and scanning is performed, sw_scan_complete callback is done after we get back to operating channel, so we do not perform queue cal work. Fix this queue cal work from sw_scan_complete(). On mt76x0 we have to restore gain in MT_BBP(AGC, 8) register after scanning, as it was multiple times modified by channel switch code. So queue cal work without any delay to set AGC gain value. Similar like in mt76x2 init AGC gain only when set operating channel and just check before queuing cal work in sw_scan_complete() if initialization was already done.

2018-11-30mt76: add support for reporting tx status with skbFelix Fietkau
MT76x2/MT76x0 has somewhat unreliable tx status reporting, and for that reason the driver currently does not report per-skb tx ack status at all. This breaks things like client idle polling, which relies on the tx ack status of a transmitted nullfunc frame. This patch adds code to report skb-attached tx status if requested by mac80211 or the rate control module. Since tx status is polled from a simple FIFO register, the code needs to account for the possibility of tx status events getting lost. The code keeps a list of skbs for which tx status is required and passes them to mac80211 once tx status has been filled in and the DMA queue is done with it. If a tx status event is not received after one second, the status rates are cleared, and a succesful ACK is indicated to avoid spurious disassoc during assoc or client polling.
