It is worth noting that the "link0" flag can be explicitly set, and will force
the card into/out of 100Mbps mode.  You'll need this, for example, if you are
using two machines plugged back-to-back with a crossover cable for testing,
or maybe for NFS.

I am about to go live with an application using >50 of those cards in 100Mbps
mode, not to mention an illegal repeater configuration ('hub and spoke' hubs
ala common 10baseT wiring); I have extensively tested all of this, and it works
fine.  I am _very, very happy_ with card, driver, and hubs; the hubs are SMC
16-port.

Now if I could just get even moderately reasonable write performance out of
NQNFS.  All it *really* seems good for is making lots of "excessive lease load
" messages pop up on the console of my NFS servers, making the client go
nuts while the server spin-locks waiting for an old lease to time out so it
can grant a new one, and occasionally crashing the machine.

Anyone got NQNFS working _well_?
