[openib-general] CMA issue: SDP login compliancy

[Michael S. Tsirkin]

Hi!
SDP compliance statement *requires* that a consumer checks the
Responder Resources field in the connection Request/Response,
verifying that it is > 0. This is part of CA 4-41 in the spec.

However Responder Resources field does not seem to be exposed by the CMA API.  I
think knowing this value (at least in REQ, but preferably in REP is well) is
also important for any ULP that does RDMA reads.

Should/can CMA/UCMA be extended to pass this to the user? This might be
something we need to address before UCMA merge to avoid ABI breakage later.
