OK attached are 4 raw tcpdumps of 1000 packets each.  One from the
start and one from steady state.

The slow set was done like this:

 on ia64:  netcat -l -p8888 > /dev/null
 on work:  netcat ia64 8888 < /dev/zero

 the traces were done of work with slow1 started right before the
 netcat on work was exectued.  And slow2 started after it acheved
 steady state at 18MB/s.

The fast set was done like this:

 on work:  netcat -l -p8888 > /dev/null
 on ia64:  netcat ia64 8888 < /dev/zero

 the traces were done of work with fast1 started right before the
 netcat on ia64 was exectued.  And fast2 started after it acheved
 steady state at 42MB/s.
