How about using ARP to get from IP to DGID+Partition
Followed by an SIDR to map DGID+PKey+Service to QKey & QP
It is the same concept as CMA that first uses IP stack (ARP etc') to get
to the remote end-point (in that case GID+PKey combination) followed by
SA-PR and CM REQ, we just substitute the CM REQ with a SIDR REQ
It may not solve all the cases but probably most of the practical ones
This was my thought as well.
Anyway the packets will need to carry some header (since it's not a
connected model), you can add more stuff in that header (e.g. can use
IPoIB header as is which contains already the src/dst IP)
I was assuming that each packet would need to carry some sort of header.
At this point, we may want to defer defining anything for UDP until there's a
better understanding of what an application would want. My guess is that such
an application will need new APIs for posting sends based on UDP addressing.
