480 * candidate. If the length is zero and the ack moved
484 * is non-zero and the ack didn't move, we're the
487 * the socket buffer and note that we need a delayed ack.
500 * If last ACK falls within this segment's sequence numbers,
514 * this is a pure ack for outstanding data.
589 * If this is a short packet, then ACK now - with Nagel
591 * he gets an ACK.
618 * If the segment contains an ACK then it is bad and send a RST.
623 * <SEQ=ISS><ACK=RCV_NXT><CTL=SYN,ACK>
682 /* ACK the SYN, send RST to refuse the connection */
745 * if seg contains an ACK, but not for our SYN, drop the input.
750 * if seg contains ack then advance tp->snd_una
826 * drop leading data (and SYN); if nothing left, just ack.
881 * Send an ACK to resynchronize and drop any data.
882 * But keep on processing for RST or ACK.
915 * (and PUSH and FIN); if nothing left, just ACK.
939 * remember to ack. Otherwise, drop segment
940 * and ack.
955 * If last ACK falls within this segment's sequence numbers,
1010 * If the ACK bit is off we drop the segment and return.
