the theoretical maximum (guaranteeing the same ber
via crc-32) is 12k. 9k is a trade-off between
this maximum and maximums of some applications
(like nfs -- 8k).

one of the first major jumbo frame pushers was
alteon.

If I'm not mistaken, 9000bytes is the max.

From acenic.c (By D.Becker of course)

 * To enable jumbo frames, simply specify an mtu between 1500 and 9000
 * bytes to ifconfig. Jumbo frames can be enabled or disabled at any time
 * by running `ifconfig eth<X> mtu <MTU>' with <X> being the Ethernet
 * interface number and <MTU> being the MTU value.

What is the largest MTU that you can use across a GigE fabric?
