We should reset mstat->airtime_ac along with clear up the entries in the hardware WLAN table for the Rx and Rx accumulative airtime. Otherwsie, the value msta->airtime_ac - [tx, rx]_last may be a negative and that is not the actual airtime the device took in the last run. Reported-by:

Do not need to check running state before configuring implicit Tx beamform. It is okay to configure implicit Tx beamform in run time. Noted that the existing connected stations will be applied for new configuration only if they reconnected to the interface.

False positive reset would be possibly triggered by those commands we applied in suspend with HZ MCU timeout, especially it happened when we enabled kernel log in pm core to diagnose how much time we spend in each driver during suspend procedure. So we enlarge the value and align the MCU timeout as other commands we did to reduce the false positive reset. Signed-off-by:

Given that there's no data coming from network stack for binding flows, hence driver counts and reports station's statistics directly through NL80211_STA_INFO_* based on active PPDU based TxS for offloading data. Apart from that, WA firmware and its offloading engine (SDO) have hardcoded "2" as PID, so we introduce MT_PACKET_ID_WED to differentiate WED reporting. Note that PPDU format TxS is mutually exclusive with MT_TXD5_TX_STATUS_HOST. Co-developed-by:

It is not meaningful to poll sta stat when there is no data traffic. So polling sta stat when the device has transmitted data instead to save CPU power. That implies that it is unallowed the stat_work to work while MCU is being initialized in the really early stage to fix the possible time to time MCU initialization failure.

Because wake_work and sdio->stat_work share the same workqueue mt76->wq, if sdio->stat_work cannot acquire the mutex lock such as that was possibly held up by [mt7615, mt7921]_mutex_acquire. Additionally, if [mt7615, mt7921]_mutex_acquire was called by sdio->stat_work self, the wake would be blocked by itself. Thus, we move the stat_work into ieee80211_workqueue instead to break the deadlock. Fixes: d39b52e3 ("mt76: introduce mt76_sdio module") Co-developed-by:

Sean Wang authored
It is unexpected that the reset work is running simultaneously with the suspend or resume context and it is possible that reset work is still running even after mt7921 is suspended if we don't fix the race issue. Thus, the suspend procedure should be waiting until the reset is completed at the beginning and ignore the subsequent the reset requests. In case there is an error that happens during either suspend or resume handler, we will schedule a reset task to recover the error before returning the error code to ensure we can immediately fix the error there.

Found by comparing with the vendor driver. Currently this affects only the RTL8192EU, which is the only gen2 chip with 2 TX paths supported by this driver. It's unclear what kind of effect the mistake had in practice, since I don't have any RTL8192EU devices to test it.

The range of calibration time of RX DCK is quite wide from ~40us to ~1300us by experiments, and probability is about 0.1% for the cases larger than 1000us. Though it can retry calibration and get positive result, it will spend more time. Therefore, enlarge it to avoid warning and duplicate calibration. Signed-off-by:
