I tried by changing my udp_server.c test line:
addr->sin6.sin6_scope_id = if_nametoindex("wlp1s0");
to
addr->sin6.sin6_scope_id =
addr->ipv6_get_netif_scope("fe80::6e29:95ff:fe7d:37e6");
and the test again worked fine:
Apr 23 08:10:41 salmon sip-proxy[21888]: Listening on
Apr 23 08:10:41 salmon sip-proxy[21888]: udp: FE80:0:0:0:6E29:95FF:FE7D:37E6
[FE80:0:0:0:6E29:95FF:FE7D:37E6]:5060
So rather than skipping link local addresses, ipv6_get_netif_scope could
be used to find the scope id.
