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

command.

Some combinations of hosts cannnot detect mt7921e after reboot. The
interoperability issue is caused by the status mismatch between host

The firmware can have the capability to manage the channel context
scheduling on multiple roles running on the device including Station,
AP and P2P GC/GO mode (will be extended based on the future patchset)
to help users sharing the network with others on a single device.
The firmware is able to support the channel chanctx up to 2 interface
simultaneously running on the different channels.
Another thing to be noted is that before the driver is going sent out the
management frames, the driver has to get the privilege from the firmware
to occupy the current channel context until the frame handshake is
completed and then get the privilege back to the firmware.
