As the VLAN insertion is partially supported in vector path,
the behavior is different in scalar and vector path.
For a VLAN packet, if using scalar path, the new VLAN tag will
be inserted after the original VLAN tag. If using vector path,
the new VLAN tag is inserted before the original VLAN tag.
To avoid any misleading, disable VLAN insertion in vector path.
