The kernel used to let me bind(2) to an IPv6 interface---e.g., [sin6_addr
fe80::200:24ff:fec3:4bac sin6_scope_id 1]---and sendto(2) the destination
[sin6_addr ff02::2 sin6_scope_id 0]. I cannot do that any longer. Now,
sendto exits with EHOSTUNREACH.
I would expect sendto to fail if I hadn't bound the interface and/or set
the multicast interface with setsockopt(,IPPROTO_IPV6,IPV6_MULTICAST_IF,),
but I have done both. The new behavior seems like a regression to me.
