The proposal lets you share any object across processes, same as we can do
across threads at the moment, potentially with any hardware that supports IB
spec 1.2. This can be used for both send and receive queues, CQs, etc.

SRC is a separate hardware extension. Speaking about "SRC without
hardware support" simply does not make sense to me.
