I'd be surprised. I _guess_ you mean the if_link of macvlan, that is unfortunately not just macvlan, but because of netns isolates from L2, it is purely a display problem, macvlan should work well, just its netlink dump is confusing. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
