    Subject[PATCH 4.13 15/44] net: bridge: fix returning of vlan range op errors
    Date
    4.13-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Nikolay Aleksandrov <nikolay@cumulusnetworks.com>


    [ 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")
