It receives its own neighbour solicitation (multicast) packets when the
AP sends them back out again. These packets...

You should be able to see this without _any_ IPv6 infrastructure -- and
you'll see the link-local IPv6 address remains 'tentative'.

(radvd) to give you site-local addresses is fairly trivial too -- and
then you can also check that Ethernet multicast is working properly.
