Most/all current Foundry and Extreme switches do (ok, so this isnt 
exactly cheap gear, but its out there). I haven't had any problems with 
any of our SGIs (fibre and copper NICs) nor with any of the PC cards we 
use at work.

The JetCore based Foundry gear will fragment the packets back into 
smaller fragments for non-jumbo frame supporting gear as well, which rocks.

Simply changing to a 9000 byte MTU on our NetApp, Onyx3 and switch, the 
the NFS throughput doubled, and it took all of 5 minutes. (yes, for any 
real work we use HIPPI on the Onyx3)
