I think this is the normal naming convention used for VLAN interfaces, at least
in normal distros. It is also what the interface gets named in the output of
`ip link` when I create a `network-link` called "management".

Yes, that is the example I have based my config on.

Thanks, I tried that but it gave the same type of error. When trying to start
the networking service I get an error "#<&netlink-response-error errno: 17>",
which, from what I can tell, means file exists.

I think it might have problems creating multiple VLAN interfaces on the same NIC
for some reason.

Also, when using your config above, only one of the VLAN interfaces are created,
and it is named "enp4s0f1.3@enp4s0f1" in the output of `ip link`.

I can't do that, since this is the interface I use to log in to the machine.
And, this part is actually working, so there should be no reason to remove it.
