Controller support problem (separate report) prevents establishment of
environment.  Gateway 2000 G6-266 Pentium II, 3Com Etherlink III
(3C509) ISA Combo card (PnP disabled).
>Description:
Same as for kern PR# 4328, dated 1997-08-17, using Intel
EtherExpress Pro 100B.
>How-To-Repeat:
Install system on a 10+MBPS network; ftp to a known, uncongested
site and transfer a large file.  Use etherfind or snoop to observe packet
sizes and transfer rate.  I used the default MTU of 1500.
>Fix:
See kern PR# 4328.
