I'm interested in why your advice differs from that of the IEEE 802.3ab
spec.

Unless I'm interpreting this doc incorrectly....

"Selecting 1000BASE-T mode of operation still requires that
Auto-Negotiation be used. 
This can be accomplished by continuing to use Auto-Negotiation while
limiting the 
advertising to 1000BASE-T capabilities."

 <snip> 
The speed is usually set to either 100 meg or 1000 meg (gigabit) in
today's networks. Again hard code both the speed and duplex mode for
each switch port and NIC to make sure both connections are set to the
same. DO NOT hard code only one side of the connection be it either just
the NIC or switch port. This results in a duplex miss-match in most all
cases. 
If duplex mode of these settings is mismatched, then no or very little
data can be transmitted and servers or client PCs will fail when they
try to send data through the network.
Flow control can hard coded also but if left to auto negotiate and if it
doesn't link up correctly you should see a lot of input errors on either
the NIC or switch port. 
Finally you may have to tune the NIC to the OS particularly with GIG
NICs being they have a higher demand on OS resources. You should engage
your system vendor for how to best tune the OS to the NICs.
