MTU tuning?

[Don Holmgren]

Should I be able to successfully use MTU values other than
1500?  Using the "mtu=" option when loading the yellowfin
driver works, as reported by 'ifconfig'.  However, subsequent
ttcp or netperf tests hang.  I'm using two GNIC's back-to-back,
and have tried MTU's of 2000 and 9000.
