In addition to the previous series I posted, over time I'd
also like to get rid of the iflist_mtx in mac80211. That
isn't easy now since lots of places use iteration and would
have to be audited, but even a cursory look suggests that
mt76 might be more problematic than most since holding the
wiphy lock for the latency-sensitive pre-TBTT work could be
an issue.
Convert the pre-TBTT work to use atomic iteration and then
sending the device commands outside of it.

When drv_tx calls race against local tx scheduling, the queue fill status checks
can potentially race, leading to dma queue entries being overwritten.
Fix this by deferring packets from drv_tx calls to the tx worker, in order to

It turns out that the code in mt7603_rx_pse_busy() does not detect actual
hardware hangs, it only checks for busy conditions in PSE.
A reset should only be performed if these conditions are true and if there
is no rx activity as well.
Reset the counter whenever a rx interrupt occurs. In order to also deal with
a fully loaded CPU that leaves interrupts disabled with continuous NAPI
polling, also check for pending rx interrupts in the function itself.
