Nope, a consumer has to say whether an active connection request is
peer-to-peer or not.  It's entirely possible for two systems to be
listening for the same service, and want to make two connections (ie
the normal TCP-like case where system A connects to port X on system B
at the same time as system B connects to the same port X on system
A).  Or the application may want peer-to-peer semantics.  There's no
way for the CM to know without being told.

My thinking was that the connection model isn't carried in the CM MADs however, so a receiving CM has to determine how to match the connection request based on what the remote user requested, which isn't known.


I guess that by not having this parameter, an incoming request could be matched incorrectly with an outgoing request, if the local listening service isn't up. I'll add a peer_to_peer parameter to ib_cm_req_param.
