>Description:
I have an Intel i82544EI 1000BASET Ethernet.  I could not get the board to
use 1000Base-T media.  It would not see carrier.  Jason Thorpe pointed out
that Gig-E basically requires Nway autonegotiation in order to function at
all and the way our manual media settings work disables autonegotiation.
>How-To-Repeat:
With the above card try to set media to 1000BaseT.  Note lack of carrier.
>Fix:
Work around is to set media to auto which uses the Nway autonegotiation.
