11 /* kdump for SGI needs MP and SP versions of rx_serverQueueEntry,
12 * rx_peer, rx_connection and rx_call structs. rx.h gets included a
13 * second time to pick up mp_ versions of those structs. Currently
14 * the affected struct's have #ifdef's in them for the second pass.
15 * This should change once we start using only ANSI compilers.
16 * Actually, kdump does not use rx_serverQueueEntry, but I'm including
17 * it for completeness.

583 * is reported in "reason" and the packet's sequence number in the packet
584 * header.seq. In addition to this information, all of the current
585 * acknowledgement information about this call is placed in the packet.
586 * "FirstPacket" is the sequence number of the first packet represented in an
587 * array of bytes, "acks", containing acknowledgement information for a number
588 * of consecutive packets. All packets prior to FirstPacket are implicitly
589 * acknowledged: the sender need no longer be concerned about them. Packets
590 * from firstPacket+nAcks and on are not acknowledged. Packets in the range
591 * [firstPacket,firstPacket+nAcks) are each acknowledged explicitly. The
592 * acknowledgement may be RX_NACK if the packet is not (currently) at the
593 * receiver (it may have never been received, or received and then later
594 * dropped), or it may be RX_ACK if the packet is queued up waiting to be read
595 * by the upper level software. RX_ACK does not imply that the packet may not
596 * be dropped before it is read; it does imply that the sender should stop
597 * retransmitting the packet until notified otherwise. The field
598 * previousPacket identifies the previous packet received by the peer. This
599 * was used in a previous version of this software, and could be used in the
600 * future. The serial number in the data part of the ack packet corresponds to
601 * the serial number oof the packet which prompted the acknowledge. Any
602 * packets which are explicitly not acknowledged, and which were last
603 * transmitted with a serial number less than the provided serial number,
604 * should be retransmitted immediately. Actually, this is slightly inaccurate:
605 * packets are not necessarily received in order. When packets are habitually
606 * transmitted out of order, this is allowed for in the retransmission
607 * algorithm by introducing the notion of maximum packet skew: the degree of
