This adds handling code to detect it in the TX path and the legacy RX path. There is no way to detect it in the vector RX path because that can legitimately return 0 even if the remote end has not closed the connection. As a result the detection is delayed until the first TX event after the close. Signed-off-by: Anton Ivanov <anton.ivanov@cambridgegreys.com> Signed-off-by: Richard Weinberger <richard@nod.at>
