Alexander V. Chernikov 1bcd230f95 netlink: add interface notification on link status / flags change. ... * Add link-state change notifications by subscribing to ifnet_link_event. In the Linux netlink model, link state is reported in 2 places: first is the IFLA_OPERSTATE, which stores state per RFC2863. The second is an IFF_LOWER_UP interface flag. As many applications rely on the latter, reserve 1 bit from if_flags, named as IFF_NETLINK_1. This flag is mapped to IFF_LOWER_UP in the netlink headers. This is done to avoid making applications think this flag is actually supported / presented in non-netlink outputs. * Add flag change notifications, by hooking into rt_ifmsg(). In the netlink model, notification should include the bitmask for the change flags. Update rt_ifmsg() to include such bitmask.
