Subject: [PATCH] interfaces: short road to PPPoEv6 interface #6245

There's a bit too much trickery involving get_ppp_parent() inside
get_real_interface() which internally calls get_real_interface()
again and produces the mismatch we see.

We can safely assume that PPPoE always has a PPPoE device like the
IPv4 case and be done with it.
