When a malicious operation is detected, the firmware triggers an
interrupt, which is then picked up by the service task (specifically by
ice_handle_mdd_event). A reset is scheduled if required.

Tx hang detection works in a similar way, except the logic here monitors
the VSI's Tx queues and tries to revive them if stalled. If the hang is
not resolved, the kernel eventually calls ndo_tx_timeout, which is
handled by ice_tx_timeout.
