Also applicable to two IB ports, e.g. forwarding SDP traffic from one IB
partition to SDP on another partition (may even be the same port with
two P_Keys), and doing some load-balancing or traffic management in
between, overall there are many use cases for that.
While I can envision how an endpoint could communicate with another in separate partitions, doing so really violates the spirit of the partitioning where endpoints must be in the same partition in order to see one another and communicate. Attempting to create an intermediary who has insights into both and then somehow is able to communicate how to find one another using some proprietary (can't be through standards that I can think of) method, seems like way too much complexity to be worth it.
