Bug Description
Starting from version 1.3.5, Libvirt allows to set a vlan tag for macvtap
passthrough mode on SR-IOV VFs. Libvirt also removes any vlan tags that
has been set externally, by the ip link command.
Due to this, it's not possible to set a vlan for VFs with macvtap.

Starting from version 1.3.5, Libvirt allows to set a vlan tag for macvtap
passthrough mode on SR-IOV VFs. Libvirt also removes any vlan tags that

In order to support the older libvirt versions, this code will make
the behaviour backward compatible by checking the libvirt version.
This can be completely removed once the minimum libvirt version will increase.
