   The numbers are packet sends/receives to user processes throught the
TCP/IP stack. I would expect the packet forwording capability to be much
greater. The majority of the CPU time is spent doing file related things,
not networking.

   10/100, one connection, one vendor. The one vendor is a good thing,
however, because the design isn't "pot luck" and the device driver is
much less complicated as well. Or in other words, good for users, bad
for Intel haters. The chip is available from Intel for people if they
want to make clone cards, however.
