Ethernet Jumbo Frames

[Rick Moleres]

Sure, it can be done.  The Xilinx 10/100 Ethernet drivers have jumbo
frame support in MontaVista/WindRiver Linux.  As long as both ends are
talking jumbo frames, works just fine.

Has anyone on this list ever been given a requirement to implement
support for ethernet frames larger than the standard MTU of 1500?  ...

... for normal 10/100 Ethernet?   ... not gigabit.

The application is to support certain encapsulation protocols without
imposing smaller than 1500 byte MTU restrictions on the innermost
protocol.

I have been tasked to investigate this for a system based on PPC405EP.
Can it be done using the IBM EMAC, Linux drivers, etc?

Regards,

Darcy
