Unless they are referring back to the mid-90's when the early PCI Ethernet 
adapters on Alphas were not-so-great, that info is a bit stale.

VMS Engineering (specifically, the guy who's been writing our Ethernet drivers 
for over 30 years) has stated that auto-negotiate should always be used.

If it doesn't work, he'll fix it, or determine that the switch is non-conforming 
to the standard.
