Thanks for answering this one Martin.

Also - we're working on a follow-on patch to the above which both
improves behaviour when the input packet rate greatly exceeds what the
system can handle, and nearly doubles the performance in forwarding of
small packets (measured in packets-per-second).

I'm currently working against 2.6.15 -- which is pretty stable for the
1480, and because it includes the oprofile changes we submitted earlier
for the sb1.

HTH,
