The goal of this commit was to have only one description instead of
two (only the first one is printed by ifconfig and dmesg).  So the
commit didn't change the existing behaviour of ifconfig/dmesg.
I can swap the two lines (make 1000baseT the description and
1000baseTX the alias), but it may break existing scripts that grep
dmesg or ifconfig output for 1000baseTX.
