This commits adds a new RDMA local service operation: - IP to GID resolution. The client request would include the ifindex of the outgoing interface and would place in an attribute (LS_NLA_TYPE_IPV4 or LS_NLA_TYPE_IPV6) the destnation IP. The local service would answer with a message that has the attribute: - LS_NLA_TYPE_DGID - The destination GID.
