Is there a way to query an ethX interface and find out if it's iWarp/RDMA capable?
Unfortunately there isn't an easy way to do this (someone should implement this as part of the rdma services!). One way you can do it is to get all the IP addresses from each interface via SIOCGIFCONF and friends, and then attempt to rdma_bind() to each address/port 0. If it succeeds, then that interface supports rdma. OpenMPI does this...
