Hah!  So much for the 3Com web page that states that you should be able to
make 20-25Mb/s.

Hm, I shuld have realized that from using the driver in the 2.4.19 kernel.
Unfortunately, the Scyld driver at ftp://ftp.scyld.com/pub/network/isa/3c515.c
does not compile with the 2.4.19 kernel.  Here is what I get:
