msk(4) will show watchdog timeouts when it detects driver TX path
is in stuck condition but I believe this has nothing to do with

There was no msk(4) code change in 10.2-RC1.  If you happen to see
the watchdog timeouts again, please try attached patch and let me
know whether it makes any difference for you.  I didn't get much
feedbacks on the patch so I'm not sure whether it really fixes the
root cause.
