Description Kurt Seifried 2015-09-30 18:40:01 UTC
It is reported that when a bridge device is set up with "None" for the boot 
protocol on a network with working IPv6 stateless configuration the host will
receieve a valid SLAAC IPv6 address. This could result in a system being 
reachable via IPv6 when it is not intended to be.
