Upgrade e1000e drivers

README.md

Upgrade e1000e drivers on Ubuntu

Simply run ./upgrade.sh.

Information

Make sure to run shutdown -r now after completing installation.

Also, use lshw -C network to verify the driver installation.

If the driver is still outdated after reboot, make sure /etc/modules contains e1000e.
