Hey, QPs are never exposed to the Eth/IP/UDP RoCEv2 network/devices, however, in most cases, to preserve ordering within QPs, QPs are mapped into 5 tuples, since the only mutable header in RoCEv2(or similar RDMA over IP/UDP protocols) is the UDP source port (destination is set to 4791), each QP between a given pair of sender and receiver gets its own UDP source port (which also allows to per QP/flow hashing in the network).
