[PATCH 4.13 15/44] net: bridge: fix returning of vlan range op errors

[Greg Kroah-Hartman]

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")
