veth and macvlan are created with
ip link add .... type veth ....
ip link add .... type macvlan ...

ppp is created normally.

I have never run lxc and find it's interface inflexible for my needs so I don't
know the specifics there.

It is the tun SETIFF ioctl that specifies which interface a tun device connect to.
But yes several tun/tap  work just in a container.
