/*
* 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.

/*
* Notes on reference tracing on ill, ipif, ire, nce data structures:
*
* The current model of references on an ipif or ill is purely based on threads
* acquiring a reference by doing a lookup on the ill or ipif or by calling a
* refhold function on the ill or ipif. In particular any data structure that
* points to an ipif or ill does not explicitly contribute to a reference on the
* ill or ipif. More details may be seen in the block comment above ipif_down().
* Thus in the quiescent state an ill or ipif has a refcnt of zero. Similarly
* when a thread exits, there can't be any references on the ipif or ill due to
* the exiting thread.
*
* As a debugging aid, the refhold and refrele functions call into tracing
* functions that record the stack trace of the caller and the references
* acquired or released by the calling thread, hashed by the structure address
* in thread-specific-data (TSD). On thread exit, ip_thread_exit destroys the
* hash, and the destructor for the hash entries (th_trace_free) verifies that
* there are no outstanding references to the ipif or ill from the exiting
* thread.
*
* In the case of ires and nces, the model is slightly different. Typically each
* ire pointing to an nce contributes to the nce_refcnt. Similarly a conn_t
* pointing to an ire also contributes to the ire_refcnt. Excluding the above
* special cases, the tracing behavior is similar to the tracing on ipif / ill.
* Traces are neither recorded nor verified in the exception cases, and the code
* is careful to use the right refhold and refrele functions. On thread exit
* ire_thread_exit, nce_thread_exit does the verification that are no
* outstanding references on the ire / nce from the exiting thread.
*
* The reference verification is driven from the TSD destructor which calls
* into IP's verification function ip_thread_exit. This debugging aid may be
* helpful in tracing missing refrele's on a debug kernel. On a non-debug
* kernel, these missing refrele's are noticeable only when an interface is
* being unplumbed, and the unplumb hangs, long after the missing refrele. On a
* debug kernel, the traces (th_trace_t) which contain the stack backtraces can
* be examined on a crash dump to locate the missing refrele.
