2023-04-17wifi: mt76: mt7921e: stop chip reset worker in unregister hookQuan Zhou1-1/+2
If the chip reset worker is triggered during the remove process, the chip DMA may not be properly pushed back to the idle state. This can lead to corruption of the DMA flow due to the chip reset. Therefore, it is necessary to stop the chip reset before the DMA is finalized. To avoid resetting the chip after the reset worker is cancelled, use __mt7921_mcu_drv_pmctrl() instead of mt7921_mcu_drv_pmctrl(). It is safe to ignore the pm mutex because the pm worker and wake worker have already been cancelled.

2023-04-17wifi: mt76: mt7921e: improve reliability of dma resetQuan Zhou1-16/+20
The hardware team has advised the driver that it is necessary to first put WFDMA into an idle state before resetting the WFDMA. Otherwise, the WFDMA may enter an unknown state where it cannot be polled with the right state successfully. To ensure that the DMA can work properly while a stressful cold reboot test was being made, we have reordered the programming sequence in the driver based on the hardware team's guidance. The patch would modify the WFDMA disabling flow from "DMA reset -> disabling DMASHDL -> disabling WFDMA -> polling and waiting until DMA idle" to "disabling WFDMA -> polling and waiting for DMA idle -> disabling DMASHDL -> DMA reset. Where he polling and waiting until WFDMA is idle is coordinated with the operation of disabling WFDMA. Even while WFDMA is being disabled, it can still handle Tx/Rx requests. The additional polling allows sufficient time for WFDMA to process the last T/Rx request. When the idle state of WFDMA is reached, it is a reliable indication that DMASHDL is also idle to ensure it is safe to disable it and perform the DMA reset.

2023-04-17mt76: mt7921: fix kernel panic by accessing unallocated eeprom.dataSean Wang1-20/+0
The MT7921 driver no longer uses eeprom.data, but the relevant code has not been removed completely since commit 16d98b548365 ("mt76: mt7921: rely on mcu_get_nic_capability"). This could result in potential invalid memory access. To fix the kernel panic issue in mt7921, it is necessary to avoid accessing unallocated eeprom.data which can lead to invalid memory access. Furthermore, it is possible to entirely eliminate the mt7921_mcu_parse_eeprom function and solely depend on mt7921_mcu_parse_response to divide the RxD header.

mt7921 just stop some workers and clean up chip status before reboot. In stress test, there are working activities still running at the period of .shutdown callback and that would cause some hosts cannot recover DMA after reboot. To avoid the floating state in reboot, we use mt7921_pci_remove() to fully deinit all resources.

Should not use AND operator to check vif type NL80211_IFTYPE_MONITOR, and that will cause we go into sniffer command for both STA and MONITOR mode. However, the sniffer command would set channel properly (with some extra options), the STA mode still works even if using the wrong command.
