The challenges with regard to adding RDMA/CM support to the SRP initiator and target drivers are: - IANA has not yet assigned a port number to the SRP protocol (see e.g. http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml). - The login request (struct srp_login_req) is too large for the RDMA/CM. A format for the login parameters for the RDMA/CM has not yet been standardized.
