5.3-STABLE/alpha: re(4) slowdown

[Christian Weisgerber]

After updating my 5.3-STABLE/alpha from Dec 4 to Dec 22 on RELENG_5,
network _receiving_ throughput on its re(4) interface has collapsed
to a maximum of 0.5-1.0 MB/s.  (Figures from scp.  Yes, I realize
this is not the most suitable test, but the box is not CPU starved
and used to receive data at several times that rate.)  I use the
machine as X11 display and quickly noticed that remote X11 apps had
become unusually slow.  IPv4 and v6 are equally affected.

There haven't been any changes to if_re.c in this period.  Any other
changes that could explain this?
