This is what I want all vendors to support. If you set 100/f hard, then
keep the autoneg going but only announce ability to do 100/f. I see no 
reason to turn autoneg off just because you have fixed both duplex and 
speed? I haven't been able to aquire an answer to the rationale vendors 
have applied when opting to disable NWay when both duplex and speed is 
fixed?
