[SOLVED] [RTL8151] Ethernet not working via multiport adapter

[TriMoon]

Hi and welcome to the forum

@tomthecat

How can I teach Manjaro / linux to use this as a ethernet adapter?

You would need to craft udev rules, i’m sure there is info on the internet about that topic, or someone here to aid in that.
You would at least need to find the adapter’s info via lspci and or lsusb and search which kernel driver supports it.
