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 majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html This correspondence, and any attachments or files transmitted with this correspondence, contains information which may be confidential and privileged and is intended solely for the use of the addressee.
