A user of ours reported an issue with p2p thunderbolt-net w.r.t. IPv6
and failure to reestablish the connection after a reboot of a peer
node, in the forum [0] and the relayed it upstream, so lets
cherry-pick those two patches to our 6.2. Especially the IPv6 one
seems straight forward, and the other one makes it actually spec
conform and should only improve things.
