[lwip-devel] [task #13512] check how IPv6 handles the "no address" case for routing

[Ivan Delamer]

Follow-up Comment #3, task #13512 (project lwip):

There should always be a LL address configured, and possibly a routable
address as well.

I'm not sure we should drop outgoing packets to an external network if we have
no routable address. In general ip6_route() will just not select that netif,
unless a router is configured.

We could add a check so that ip6_address[0] is configured.
