Hello!
Is it at all possible for a SoftRoCE node to talk to OpenSM? Can I set
up OpenSM in such a way that it automatically discovers all SoftRoCE
nodes on my subnet? Thanks for your help.
Cheers,
Christian

AFAICT, RXE lacks MAD support which is needed for OpenSM.
Thanks

All Ethernet based RDMA technologies lack MAD support required for OpenSM. OpenSM is a uniquely InfiniBand only thing.
