Are you referring here to messages of the EMAD protocol ?I know nothing about this protocol..... Does it at least use standard Ethernet framing? Source and Destination header and an EtherType which mean EMAD?
Yep, but that does not really matter. I believe we should find debugging interface which is protocol agnostic. Just arbitrary messages monitoring.
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.
