vge blackouts, "soft reset timed out"

[Andrew Pantyukhin]

I've had problems with vge before, but when I updated to
the latest current yesterday, it became nightmarish. It stops
sending/receiving every few (~5) minutes for a minute or
two. You can kick it alive with something like "ifconfig vge0
debug" and only then it prints:

vge0: soft reset timed out
vge0: link state changed to DOWN
vge0: link state changed to UP

With current from November 24 there was no such problem.
