[B.A.T.M.A.N.] Automatically starting adaptors at boot

[B.A.T.M.A.N.] Automatically starting adaptors at boot

[tjhowse]

Hello Ladies and Gentlemen,

This might be a question better suited to the OpenWRT list, but I
figure it would've been solved better here.

I've got a two-node mesh set up and working well. Config files are
below. I have some minor woes though. Each time one of the nodes boots
up I must:

brctl addif br-lan bat0
ifconfig bat0 up

...before traffic starts to flow between clients connected to the
wlan0 radios of each node. What's the best way of having this happen
automatically? I assume there's a better way than having an init
script run those commands at boot.

Please note that I'm somewhat of a networking novice, so if anything
below seems super dumb, please say so.

Thanks,
Travis.

radio0 is 2.4GHz, for connecting to clients.
radio1 is 5GHz, for the mesh interconnects.

This is totally related to openwrt and unrelated to batman-adv.

If I remember correctly you can directly configure the lan "interface" in
the /etc/config/network file. You should be allowed to specify more than one
ifname (in the same option line).

The openwrt channel/documentation can probably be more helpful.
