Do you know how to make soft-roce (on server) can send message
to the hard-roce (like Mellanox cx4 card) on a client? We tried rdma-core
25.0 and 26.0. The rdma-core can support both soft-roce and hard-roce.
But it seems that the soft-roce (server) and hard-roce (client) can not
communicate via "ib_send_bw", "ib_read_bw" and so on, but can
communicate via "rping".
Do you ever try to use soft-roce and hard-roce together?
Do they work well? I really wonder why they can not communicate with
each other. Best wishes,
I think this should be possible. The diagram on the following web page
shows a RoCE NIC and softROCE connected to each other:
