       NAME
             DLunbind_req - process DL_UNBIND_REQ primitive

       SYNOPSIS
             DLunbind_req(queue_t *q, mblk_t *mp)

          Parameters
            q           pointer to the write queue

            mp          message pointer

       DESCRIPTION
             This function processes the DL_UNBIND_REQ primitive.  The
             latter is used to unbind a SAP from a Stream.  If the state of
             the SAP is not DL_IDLE, a DL_OUTSTATE error is returned by
             calling DLerror_ack().  If there is not enough memory for a
             reply, the request is discarded.  The SAP state is reset, both
             the STREAMS queues are flushed and a reply is sent in the form
             of a DL_OK_ACK message.  The SAP is specified in host order.

          Response
            error code  DL_OUTSTATE

            DL_OK_ACK   sent upstream
