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

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