There exists a small window of time in icmp6_bind() between creating the ICMPv6 socket and binding it to an ifindex, where the link-scoped socket can process an ICMPv6 packet received on any interface. The applies to both sd-radv and sd-ndisc codepaths. This change adds an explicit check for ifindex on the receive path and ignores packets received on other interfaces.
