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