[openib-general] round 2 - proposal for socketbased connectionmodel

[Kanevsky, Arkady]

This is the whole purpose of the protocol.
It is OS independent and ensures interoperability.
Nobody will change their OS protocol implementation
so it can communicate to Linux (or any other OS or vendor)
that invented its own protocol...
It is not OS (linux no exception) job to invent protocols.

But I think this argument have been bitten enough already.
