Config
Ignoring specific devices
This is mostly taken from different parts of archwiki/NetworkManager. This is desirable so it wont interfere with our hostapd or dnsmasq config.
In /etc/NetworkManager/conf.d/unmanaged.conf :
MAC addr based:
[keyfile]
unmanaged-devices=mac:<hwaddr>
Interface name based:
[keyfile]
unmanaged-devices=interface-name:<ifname>
After modifying run
sudo nmcli general reload
Must avoid having conflicting dnsmasq instances between #systemd managed and #NetworkManager built in.
