awesome thank you, that worked but one thing so I can use something like this

Code:
#!/bin/bash

/usr/sbin/ethtool --offload enp6s0 tso off gso off gro off


but where would I put a network script to auto start on boot/login?

To do this in /etc/conf.d/net (assuming you are using netifrc with /etc/init.d/net.enp6s0):

Code:
ethtool_offload_enp6s0="tso off gso off gro off"


Then the local.d file is not necessary.
