Subject: net: bridge: fix returning of vlan range op errors
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=66c54517540cedf5a22911c6b7f5c7d8b5d1e1be;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

net: bridge: fix returning of vlan range op errors

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")
