Gigabits, watchdog timeouts and downtime, oh my!

[Brad Waite]

Hey all,

Decided to move into the Gigabit world yesterday and picked up a SMC
9452TX for my 4.10-STABLE box.  I rebuilt the kernel with the sk device
and while it works somewhat, I'm getting 'sk0: watchdog timeout' errors
and the card goes down for a few seconds before waking back up.  This
happens under relatively light traffic, too.

Suggestions?
