Subject: vlan: Correctly handle device notifications for layered VLAN devices
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=81d85346b3fcd8b3167eac8b5fb415a210bd4345;p=mv-sheeva.git

vlan: Correctly handle device notifications for layered VLAN devices

Commit 30688a9 ([VLAN]: Handle vlan devices net namespace changing)
changed the device notifier to special-case notifications for VLAN
devices, effectively disabling state propagation to underlying VLAN
devices. This is needed for layered VLANs though, so restore the
original behaviour.
