interface: Allow VLAN tag-rewrite on non-sub-interfaces too.
This fix was first made in commit fdea5c6a00b74971dbb1b7ec4e25839a871006ca but was subsequently lost in commit 053204ab039d34a990ff0e14c32ce3b294fcce0e Added unit test for setting VTR on a non-sub-interface to help ensure no future regressions of this ability. Type: fix Change-Id: I71ce2684fb72383741455829ae2d397ea2e95eae Signed-off-by: Jon Loeliger <jdl@netgate.com>
