Re: [PATCH] babel: Initialise source seqno from incoming message

This has been clarified in RFC8966 as: "Note that the feasibility distance is not updated and the garbage-collection timer is not reset when a retraction (an update with infinite metric) is sent."

The feasibility distance is only updated if the metric is lower, which is never true for an (infinite-metric) retraction, so that's kinda implicit anyway.

We do actually update the garbage collection time regardless of the route metric in the regular update function (but not when sending an explicit retraction). I think that's OK, though?

Does that mean that a retracted route never expires? -- Juliusz
