Thanks I saw the intr call in the trace and assumed wrong, the 'lltable'
should have tipped me off.

I haven't tried that lately in -current, last time I did that msk did
not work at all. Will retry and report back.

Yes, this box runs -current constantly, only recently did I have to
give up my dual Intel adapter and go back to using the on-board
pci-e yukon, and thus re-experiencing this issue.

It still repros on -current, hence me trying out the experimental
patches in the PR and reporting back. As I reported in this PR
earlier I could still hit the watchdog after a week of runtime, but
as of now I don't have a reliable repro.
BTW thanks for all your hard work on hardware NIC support. Very
much appreciated.
