All in all, when non default interface is needed/used (e.g for

Do you mean you need a src IP for rdma_resolve_addr? If so, if you have
a src ip, can you override what rdma_resolve_addr gives you for cases
like where you have two ports on the same subnet?
Oh yeah, if you are wondering, for iscsi_tcp iface binding there is a
sockopt to tell the network layer to forget what it would do (use the
route table) normally, and instead send IO through the netdev we pass
it. So in userspace we use the netdev we have from iface.net_ifacename
or match the MAC with a netdev and then pass that to the sockopt. Do you
have something similar for ib?
