Gregory Nutt 361d85ae35 net/tcp and udp: Fix errors in the new implementation of SO_LINGER. The tcp_drain() and udp_drain() functions were casting the working argument to the wrong type, resulting in hangs and abnormal behavior. There is a complexity in the tcp drain logic when the remote peer closes the socket before all Tx data has been flushed. Sometimes we are not notified of this case and wait the entire timeout unnecessarily. There is a workaround in place in tcp_txdrain(), but this really should be revisited.
