Support adding static router advertisments

[ntninja]

Basically I want to be able to replace this radvd configuration snippet:

interface br-lan
{
        AdvSendAdvert on;
        AdvManagedFlag off;
        AdvOtherConfigFlag off;

        route fc00::/8
        {
                AdvRoutePreference medium;
        };
};

It statically advertises a route for the fc00::/8 address space on all LAN interfaces, nothing else; no assigning addresses, no extra subnet routes, just handing out that single route. This this possible with odhcpd right now? Is it hard to implement?

Need this too. Was shocked to find that radvd got removed from OpenWRT, while its "replacement" odhcpd doesn't even have this basic feature.

This is a very important feature. How can this be implemented?

Meanwhile this package can be used instead https://github.com/ffulm/firmware/tree/master/package/simple-radvd
