I think we should follow up on something Fran=C3=A7ois-Xavier Le Bail p= roposed here: http://patchwork.ozlabs.org/patch/294029/ In general I like the idea, and I also agree with David, we should disa= ble it by default. But this would be beneficial to NetworkManager to not ne= ed to set temp_addresses to 2 to have them used by default. I guess a netl= ink api and a per-interface flag would be the easiest thing for NM to handl= e? Greetings, Hannes
