4.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nikolay Aleksandrov <nikolay@xxxxxxxxxxxxxxxxxxx>
[ Upstream commit 66c54517540cedf5a22911c6b7f5c7d8b5d1e1be ]
When vlan tunnels were introduced, vlan range errors got silently
dropped and instead 0 was returned always. Restore the previous
behaviour and return errors to user-space.
Fixes: efa5356b0d97 ("bridge: per vlan dst_metadata netlink support")
