Fix e1000 network hangs

Under some conditions, intel e1000 and e1000e network cards can cause hangs. To fix this on debian-ish systems, disable tso and max out the rx and tx values.

IMPORTANT: Please ensure you are on an up-to-date kernel before trying this! Confirmed working with 5.15, and if memory serves 5.12 did NOT work!!

This can be done by creating /etc/network/if-up.d/e1000e-fix with the following contents and making it executable (change the interface name as needed):

#!/bin/sh

ethtool -G enp0s31f6 rx 4096 tx 4096
ethtool -K enp0s31f6 tso off

This will set the correct parameters once the enp0s31f6 interface is up. Remember to adjust the interface name in the above script as needed!
