With this patch you can auto-configure your router at the first boot by
the MAC address or a random number.
To use it write a own config-package with a executable file paced
in /etc/default/autoconf witch looks like this:
config 'interface' 'lan'
option 'netmask' '255.255.255.0'
option 'ipaddr' "10.$LAN4.$LAN5.1"
option 'ip6addr' "fdcc:93c9:77b3::$WLAN0_HEX_IPV6$WLAN1_HEX:
${WLAN2_HEX}ff:fe$WLAN3_HEX:$WLAN4_HEX$WLAN5_HEX/64"
option 'dns' '85.214.73.63'
For LAN MAC use LAN as varname prefix, for an random number use RAND.
