2019-02-18mt76: measure the time between mt76x02_edcca_check runsFelix Fietkau
Based on system load and time needed by other calibration runs, the time between dev->mac_work runs can vary quite a bit. Calculate busy time based on the actual time difference in order to avoid potentially over-estimating busy time, which could lead to unnecessary tx blocking.

2019-02-18mt76: run MAC work every 100msFelix Fietkau
ED/CCA Tx blocking checks need to be run every 100 ms in order to avoid triggering too late and keeping tx blocking on for too long Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76x02: use commmon add interface for mt76x2uStanislaw Gruszka
Since we now support mt76x2u feature to allow set mac address when creating interface in common code we can use it for mt76x2u. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-02-18mt76x02: use mask for vifsStanislaw Gruszka
Use vif_mask to count interfaces to allow to set mac address in HW if there is only one interface and report error if we create interface with wrong BSSID resulting in already used index. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-01-11mt76: mmio: introduce mt76x02_check_tx_hang watchdogLorenzo Bianconi
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. For the moment run mt76x02_check_tx_hang watchdog just on mt76x2 devices since the issue has not been observed on mt76x0 driver yet Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-01-11mt76: add energy detect CCA support to mt76x{0,2}e driversLorenzo Bianconi

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.
