66 * This structure is used to represent the current state of the system. We
67 * maintain these for IPv4 as proxies for links in the system. This is
68 * differentiated from the LLP which contains the intended configuration of
69 * the system.
70 *
71 * Currently these are stored on ifs_head with the wired interfaces sorted
72 * together and the wireless ones sorted together with ifs_wired and
73 * ifs_wireless pointed at these sublists. Access to these lists is not
74 * currently MT-safe.
75 *
76 * We explicitly do not maintain IPv6 interface structures. In the current
77 * state machine, IPv6 interfaces are completely dependent on their IPv4
78 * counterparts. For example, we make a decision to bring up an interface
79 * based on routing socket messages read from an AF_INET socket; we will
80 * always bring up v4, and may additionally bring up v6. Also, when we
81 * start up, we find all interfaces in the system by doing 'ifconfig -a
82 * plumb', which will plumb v4 on all links; we always keep the v4 interface
83 * plumbed, taking it up and down depending on whether it's currently in use
84 * or not. v6 interfaces are not plumbed initially; when we decide a link
85 * should be active (and its llp tells us to do v6), we'll mark the (already
86 * existing) v4 interface up, and 'plumb up' the v6 interface. Conversely,
87 * when a link is no longer active, we 'down unplumb' the v6 interface, but
88 * only 'down' the v4 interface.
