I want to know how work and what I have to configure the kernel module of BATMAN Gateway.

Hm, I am not really sure if I understood it right - you want to use batman advanced to access another network (internet....), correct? Just insmod it everywhere, add outgoing interface to /proc/net/batman- adv/interfaces and let one machine (router to the internet for example) play the dhcpd. This machine should only deliver new ip addresses to the other machines and inform everyone else that they should use his ip as default router. Then you must know if you want to use it as nat or as normal router ( just enable ipv4_forward). So it is just the same procedure as building a normal openwrt router/gateway with the small difference that all "clients" are talking over the bat0 interface instead of the wlanX/ethY interface. It is nearly the same as configuring a normal openwrt. So parts of http://wiki.openwrt.org/OpenWrtDocs/Configuration can be used.

Setting up the wifi should be the same as always: wlanconfig ath0 create wlandev wifi0 wlanmode adhoc iwconfig ath0 essid testnet iwconfig ath0 ap 02:00:de:ad:be:ef iwconfig ath0 channel 10 ifconfig ath up insmod batman-adv-core echo "ath0" > /proc/net/batman-adv/interfaces

(maybe I got it right... don't have the hardware to test it now).

I'm using OPENWRT and I haven't found paper that describe this kernel module (usage, configuration, how work).

http://tinyurl.com/6dbws8 But I am relative sure that you have read it because you have reported a bug when somebody tries to add new interfaces to /proc/net/batman-adv/interfaces.

Please ask a little more specific if I didn't answer your question. And feel free to write your setup down (small howto or so) so other people can access you knowledge afterwards (maybe marec can add it to the trac wiki).
