pxeboot with jumbo frame network

[Robert Blayzor]

Is it possible to PXEboot a diskless client with an MTU higher than 1500 (Ie: 9k) ?

The network we currently boot several diskless machines from has a lot of NFS traffic and we'd like to enable them all for larger MTU's however the one thing stopping us is the issue with initial boot seemingly only supporting an MTU of 1500.  

I know we can set the MTU later (post boot) on the diskless machines, but it doesn't seem we can run a higher MTU on the TFTP server as we'd have TFTP UDP traffic with mis-matched frame sizes at that point.
