Alright.

We clean leave it for later indeed, but in case you're wondering -
that's unlikely to fly. My preference will be to expose the accelerator
port as a switch port, with a netdev and forward using TC flower etc.
With the netdev in place you'll have a place to report stats and all the
necessary diagnostics, which otherwise get crammed into random places.
I believe Florian asked about this in the past, I hope I'm being
consistent with my answer here :P
