[LEDE-DEV] [PATCH] kernel: Activate CONFIG_BRIDGE_VLAN_FILTERING

[Hauke Mehrtens]

This allows to configure VLAN aware bridges in Linux, it is also
possible to offload these VLAN aware bridges with DSA to some hardware,
which is supported by most of the DSA drivers.

This adds support for the VLAN features mentioned in bridge man page:
http://man7.org/linux/man-pages/man8/bridge.8.html

This increases the kernel size of an lzma compressed Lantiq xrx200
kernel by 4.774 Bytes.

Without brdige vlan:
1.771.351 bt_homehub-v5a-kernel.bin

With brdige vlan:
1.776.125 bt_homehub-v5a-kernel.bin
