Sorry, I erred by assuming that each command is delivered in a separate TCP
segment which is how I would have done by implementing the TCP in an
adapter.  BTW, may be I should bring up my old broken tune.  Have anyone
thought about the amount of TCP buffer needed for a one Gb network with 160
msec roundtrip time?  It is 16MB.  If we have a missing ACK, the buffer need
be very big or the wait would be very long.  The ten Gb Ethernet is coming
very soon!
