Examples do help a lot. I do use the enp* naming scheme. My
understanding, that is the "new" way. Based on your config, I would
need to change the NAME= to enp* names and that would correct that.
Where you have ATTR, is that a quote or did you edit to remove a number,
MAC address, IP or something? If it is one of those, where do I find
that info? I checked ifconfig and didn't see a MAC address. I also
checked lspci -v. I'm not sure where you get the needed info from.
BTW, right now, I'm on my main rig.
I have the package net-misc/networkmanager installed. Most likely
pulled in by something else. Could I use it to configure this? I also
have KDE installed on the NAS box, it is also a backup rig in case my
main rig dies. It may have a GUI that I could use. I'm not opposed to
the command line way tho. Biggest thing, copy and paste would be nice.

I'm trying to hoe weeds in my garden at the moment. Hoe a little, take
a break, then repeat. I did sharpen the edge on my hoe tho. If I touch
it, it's cut. Makes it a lot easier.
Thanks.
