History
Pyun YongHyeon c68ea28fe1 It seems that em(4) misses Tx completion interrupts under certain 
conditions. The cause of missing Tx completion interrupts comes from
Tx interrupt moderation mechanism(delayed interrupts) or chipset bug.
If Tx interrupt moderation mechanism is the cause of false watchdog
timeout error we should have to fix all device drivers that have Tx
interrupt moderation capability. We may need more investigation
for this issue. Anyway, the fix is the same for both cases.

This should fix occasional watchdog timeout errors seen on a few
systems.
