I like larger MTUs, and used to call stateless offloads like TSO/GSO 
"Poor man's Jumbo Frames" but if you can get the stateless offloads 
going, you can go beyond the savings one gets from JumboFrames because a 
TSO/GSO/GRO "segment" can end-up being semi-effectively 32-64KB.

PS - don't forget that *everything* in the same broadcast domain must 
have the same MTU
