Hi

My msk0 (Marvell Yukon 88E8053 Gigabit Ethernet) will stop working
and never recover after a burst in activity.  It produces the
following messages:

Dec 23 15:24:16 apple kernel: msk0: watchdog timeout
Dec 23 15:24:16 apple kernel: msk0: link state changed to DOWN
Dec 23 15:24:19 apple kernel: msk0: link state changed to UP
Dec 23 15:24:29 apple kernel: msk0: watchdog timeout (missed Tx interrupts) -- recovering

pciconf -lvc:
