Please found a serie improving documentation of bridge device.

Please review and apply

I could not understand some options in this page:
- vlan_tunnel on  ? 

According to https://vincent.bernat.ch/en/blog/2017-linux-bridge-isolation
I need  echo 1 > /sys/class/net/br0/bridge/vlan_filtering to enable vlan filtering

Do we need the echo 1 ? Or could be implemented by ip bridge (better for user experience) ?
