NettetAF_RXRPC provides: Part of an RxRPC facility for both kernel and userspace applications by making the session part of it a Linux network protocol (AF_RXRPC). A two-phase protocol. The client transmits a blob (the request) and then receives a blob (the reply), and the server receives the request and then transmits the reply.
