Option to define address of router in the RA
It must be possible to define what address you want to use in the RA. My understanding is that right now, the RA takes the link-local address automatically created with the Interface ID.
However in many other platforms, is possible to decide if you want to use the Interface ID or something different, for example, I want to use FE80::1.
Right now it seems not possible.
Using list ip6addr 'fe80::1/64', in the given interface, will work for now if you manually configure FE80::1 as the default GW in client machines, but the RA still uses the Interface ID.
I haven't looked into this in detail, but I have a hunch that it'd be better to add support to netifd to set a specific (similar to an IPv6-Token) style link-local address for a given interface. That way you can have memorable addresses like FE80::1 without having to resort to multiple link-local addresses or any changes to odhcpd.
