OLSR on Android

The current firmware does not support broadcast and multicast.
Fortunately, there exists a firmware on Android that allows the cellphone to work on Infrastructure and hence, allows to work on Ad hoc mod.

The two commands to issue:
1. rmmod bcm4329
2. insmod /system/lib/modules/bcm4329.ko firmware_path=/etc/firmware/fw_bcm4329_apsta.bin
and that's it

To install OLSR, make sure to use the latest version. (6.1)

PS: edit as well /data/misc/wifi/wpa_supplicant.conf with the proper essid
