Hmm, arent you posting to wrong list? ;)
You really dont want a Linux switch, least not with common
desktop/server orientated NICs. You'd want the actual switching
offloaded. (funnily enough, Linux /used/ to be able to do something
vaguely like this, with certain NICs, but that's deprecated now,
possibly gone completely - direct NIC to NIC transfers, tulip
supported it - no idea if it worked well, and you obviously couldnt
do anything firewalling.).
What you /really/ want is a good L3 switch, or a pair of them, that
speak a decent routing protocol so that your linux boxes can tell
them where to direct traffic..
