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.
