IPv6 multicast packets going through different interfaces than specified by routes
Issue
- On a system with multiple interfaces, inserting a route for a specific multicast address doesn't work and the packets go out through another interface
- The application doesn't use IPV6_MULTICAST_IF socket option to select the outgoing interface - see ipv6(7)
