I know nothing about this protocol.....

Does it at least use standard Ethernet framing? Source and Destination
header and an EtherType which mean EMAD?

Marvell has a way to access registers of their switches using Ethernet
Frames, and they are valid frames with a specific EtherType. Linux
does not use them, but if it did, i would of thought passing them
along using the normal pcap interface would be trivial.
