The responder then waits for a new request packet.\n\ncommit 689c5421bfe0 (\"RDMA/rxe: Fix incorrect responder length checking\")\ndefers responder length check for UD QPs in function `copy_data`.\nBut it introduces a regression issue for UD QPs.\n\nWhen the packet size is too large to fit in the receive buffer.\n`copy_data` will return error code -EINVAL.
