[RFC PATCH] fff-batman-adv: Disable batman gw-selection

[Fabian Bläse]

For our centralized setup, batmans gateway selection
makes way more problems than it solves for various reasons.

Mainly a broken DHCP server is not recognized by it, therefore
nodes might select a gateway with a broken dhcp server.
Routers have to run a cronjob every minute to reevaluate
gateway metrics because of weird refresh behaviour with specific
client modes.

Also, gateway selection violates the OSI model by
tampering with protocols on a different layer.

When disabling it, every DHCP Server will reply to a clients request
and the client decides which offer it is going to use. Typically the
first response is used.
