[if_re] Dropping connectivity

[A.J. "Fonz" van Werven]

It seems like recent commits may have broken if_re.

After I updated last weekend (and again this morning), everything appears
to be fine initially: I can ping hosts, browse the Web with Lynx, etc. But
as soon as a certain amount of data has been transferred (e.g. when I
start a graphical browser like Opera or Seamonkey, or I (try to) run port-
snap) suddenly all connectivity vanishes: resolving no longer works, I
can't even ping my modem/router. Running /etc/rc.d/netif restart doesn't
help. I do get lots of watchdog timeout messages on the console.

Fortunately I still have a USB WiFi adapter I can use (if_rum still works
like a charm) so I'm not entirely cut off, but *some*thing appears to have
happened to if_re.

Any thoughts? Thanks in advance,

Alphons

P.S. In case it matters:
