[Voyage-linux] bridge wlan eth [ 0.7.5 ]

[Punky Tse]

Hi Davide,

If you want it bridged, your bridge interface has to be ipv6.  So you 
need to change br0 instead of wlan0.

I'm a bit confused regarding the bridge interface usage. In witch subnet it supposed to be? does it has to be in a separated one? I'm googoling but I haven't get it yet.
