Killer E2400 nego 100mbps under arch but 1000mbps under livecd and win
I got a laptop with E2400. Os are `Archlinux` and `Windows`.
It performs 100 mbps speed under Arch.
The interesting thing is it can perform 1000mbps under Archlinix livecd(Release about 2018-10-1) and Windows 10.
ethtool output:

Tried. Invalid argument. Had added -s in ethtool parameter.
