There's some work going on with this at the moment ;

Currently, your choice is between full-on CPU-based firewalling and
routing, or simple card-to-card Fast Forwarding (which apparently
handles 100Mbps of 64byte packets just fine on a suitable machine -
a P90 may not suffice...).

This new stuff is about adding a congestion feedback machanism to
the drivers - they're currently working with tulips including the
funky 4 port DEC21143's.
