The AViiON gets the same packets alright; it's just that it's
interpretation of the TCP/IP spec is that if it sends an ack for
sequence number X, then the transmitting host will eventually send a
packet *beginning* with sequence number X (rather than linux's
interpretation, which is to send a packet *containing* sequence number
X). Ideally, the AViiON should extract whatever bytes in a packet it
can use, regardless of where in the sequence the packet starts; also
ideally, Linux should send a new packet whose sequence starts at the
last ack received, reducing duplication of bytes sent over the net
(which may have a performance win for slow serial links).
