NetworkManager - Ignore device

Hey all, what's the current way to disable NetworkManager from managing a device?
I've tried the keyfile plugin with unmanaged-devices=mac:mac_here and it doesn't work..
It sometimes changes the status from unmanaged -> unavailable due to reason: managed (from NetworkManager --debug)

Do you have to include the interface name as well as the mac address?

OK, what you're experiencing is not normal, because I have just edited /etc/NetworkManager/NetworkManager.conf on my Clevo W230SS laptop (Gentoo amd64) to make my wireless interface unmanaged, and that works in my case (I tried with both networkmanager-1.0.2-r1 and networkmanager-1.0.6):

It's weird..
Here it reads the information from

No, I'm using OpenRC. I suppose you could try with the so-called predictable network interface name to see if it makes a difference. BTW, isn't the file name /etc/NetworkManager/nm-system-settings.conf obsolete? I think these days it should be /etc/NetworkManager/NetworkManager.conf. For example, the command 'man NetworkManager.conf' works for me, but the command 'man nm-settings.conf' returns 'No manual entry for nm-settings.conf'.

Another thing you could investigate: I switched to using dhclient instead of dhcpcd some time ago because dhcpcd stopped working with NetworkManager for some reason (I have no idea why). Which DHCP client are you using? You could try switching to see if that makes a difference (although I doubt it). If you have USE="dhcpcd -dhclient", re-merge networkmanager with USE="-dhcpcd dhclient".

Perhaps it has something to do with SystemD that it reads the config from another file, anyways I've got them with the same content..
Tried the predictable names, it didn't work..
Also, not using DHCP et all so that can't be it either..

I wonder if something in the system-connections file could interfere with what you have in your /etc/NetworkManager/NetworkManager.conf file? Below is an example of a system-connections file on my laptop:
