RoCE v2 is really Infiniband over UDP over IP. Why don't we just call it IBoUDP like it is? IBoUDP changes the Ethertype, replaces the network header, adds a new transport protocol header, and layers IB over that. This change should be exposed properly and not as just a new GID type. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
