49  * Interface flags actually represent the state/properties of 3 different
50  * abstractions of interfaces in IP. Interface flags are set using
51  * SIOCS[L]IFFLAGS ioctl. The three abstractions are :
52  *
53  * 1) Physical interface (phyint) : There is one phyint allocated common
54  *    to both IPv4 and IPv6 physical interface instance.
55  *
56  * 2) Physical interface instance (ill) : This encompasses all the state
57  *    that is common across all IP addresses assigned to a physical
58  *    interface but different between the IPv4 and IPv6 instance.
59  *
60  * 3) Logical interface (ipif) : This has state about a single IP address.
61  *
62  * Values for the various states are derived from the same name space
63  * as applications querying the state using SIOCGIFFLAGS/SIOCGLIFFLAGS
64  * see only one state returned in lifr_flags which is a union of all
65  * the above states/properties. Thus deriving the values from the common
66  * name space makes implementation easier. All these values are stored in
67  * uint64_t and any other structure/code using these flags should use
68  * uint64_ts.
69  *
70  * As we maintain the interface flags in 3 different flags namely
71  * phyint_flags, ill_flags, ipif_flags we define the following flag values
72  * to be used within the kernel to reduce potential errors. The ones
73  * starting with PHYI_ are supposed to be used with phyint_flags, the ones
74  * starting with ILLF_ are supposed to be used with ill_flags and the ones
75  * starting with IPIF_ are supposed to be used with ipif_flags. If you see
76  * any code with a mismatch i.e phyint_flags & IPIF_UP - it is wrong. Only
77  * PHYI_XXX can be used with phyint_flags.
78  *
79  * NOTE : For EVERY FLAG in if.h, there should be a corresponding value
80  * defined HERE and this is the one that should be USED within IP. We
81  * use IFF_ flags within IP only when we examine lifr_flags.
