Oops!  There may be a problem here with radvd!.

I have difficulty in understanding why one would define multiple IPv6 
(or even IPv4) subnetworks on a single interface.  Well, I guess the 
radvd authors did also: the AdvManagedFlag on/off applies to the entire 
interface and no a specific network.

I am verifying this but there is a chance that dsnmasq could support 
both for different subnetworks.

I guess that dnsmasq could be used to support one and radvd used to 
support the other but ???

I believe this may need more discussion from others.  I would like to 
have someone other than the two of us chime in on this.
