Is it possible to create a QinQ vlan interface with libnl? As far as I can see the VLAN API doesn't support this (https://www.infradead.org/~tgr/libnl/doc/api/group__vlan.html). I know it's possible via netlink like iproute2 does it, but can't figure out how to do it with libnl... Any hints would be appreciated. Thanks in advance -- Filip
