No router advertisements on tunnel interfaces #94

The upstream commit 0c4dfeb ("improve multicast check, remove broadcast check") forces UnicodeOnly if an interface does not support IFF_MULTICAST. This stops periodic RAs being sent over tunnels, which previously used to work. The solution is to allow sending such multicast packets over point-to-point links. This is acceptable for directly connected devices, or for tunnels, the packets are encapsulated and so look like unicast packets to intervening routers.

@robbat2 hi - are you planning to do a new bugfix release anytime soon? There's a few fixes queued up, and it would be great to have them included in Debian 10 which will start freezing in a few months. Thanks! |

Patch is in Debian. Cheers |
