I'm seeing an odd thing here.  I have two NetBSD machines connected by
Netblazers and a T1 link.  Neither NetBSD machine is routing anything.
UDP connections between the NetBSD machines are normal speed, but TCP
connections have horrible delays and move data at ~400 bytes/sec.

TCP connections between a NetBSD machine and an Ultrix machine which
cross the T1 link (and also ones that don't) are fine.  It is only
when NetBSD is on both ends and the T1 in the middle that the slowdown
occurs.  This is with NetBSD-current (about 4 days old).  The same
thing happens with a 56K line rather than a T1, and also when one or
both machines run NetBSD 1.0.

Any ideas of what I should look for?  netstat -m doesn't show anything
alarming.

Oh; these are all x86 machines.
