-.Cd options RADIX_MPATH
-.Sh DESCRIPTION
-The kernel uses a radix tree structure to manage routes for the
-networking subsystem.
-If compiled with
-.Cd options RADIX_MPATH
-kernel may maintain several independent forwarding information databases (FIBs).
-The
-.Fn rtalloc
-family of routines is used by protocols to query these structures for a
-route corresponding to a particular end-node address, and to cause
-certain protocol\- and interface-specific actions to take place.
-.Pp
-The
-.Fn rtalloc1_fib
-function is the most general form of
-.Fn rtalloc ,
-and all of the other forms are implemented as calls to it.
-It takes a
-.Fa "struct sockaddr *"
-directly as the
-.Fa dst
-argument.
-The second argument,
-.Fa report ,
-controls whether the routing sockets are notified when a lookup fails.
-The third argument,
-.Fa flags ,
-is a combination of
-the following values:
-.Bl -item -offset indent
-.It
-.Dv RTF_RNH_LOCKED
-indicates that the radix tree lock is already held
-.El
-.Pp
-The last argument
-.Fa fibnum
-specifies number of forwarding information database (FIB) on which
-the lookup should be performed.
-In case of success the
-.Fn rtalloc1_fib
-function returns a pointer to a locked
-.Vt "struct rtentry"
-with an additional reference.
-.Pp
-The
-.Fn rtalloc_fib
-is the most simple variant.
-Its main argument is
-.Fa ro ,
-a pointer to a
-.Fa "struct route" ,
-which is defined as follows:
-.Bd -literal -offset indent
-struct route {
-	struct rtentry *ro_rt;
-	struct llentry *ro_lle;
-	struct sockaddr ro_dst;
-};
-.Ed
-.Pp
-Thus, this function can only be used for address families which are
-smaller than the default
-.Ft "struct sockaddr" .
-Before calling
-.Fn rtalloc_fib
-for the first time, callers should ensure that unused bits of the
-structure are set to zero.
-The second argument
-.Fa fibnum
-is FIB number.
-In case of success of the
-.Fn rtalloc_fib
-the
-.Fa ro_rt
-points to a valid and unlocked
-.Xr rtentry 9 ,
-which has an additional reference put on it, freeing which is
-responsibility of the caller.
-On subsequent calls,
-.Fn rtalloc_fib
-returns without performing a lookup if
-.Fa ro->ro_rt
-is non-null and the
-.Dv RTF_UP
-flag is set in the rtentry's
-.Fa rt_flags
-field.
-.Pp
-The
-.Fn rtalloc_ign_fib
-function is the same as the
-.Fn rtalloc_fib ,
-but there is additional
-.Fa flags
-argument, which is same as in
-.Fn rtalloc1_fib .
-.Pp
-The
-.Fn RTFREE_LOCKED
-macro is used to unref and possibly free a locked routing entry
-with one our reference, for example previously allocated by
-.Fn rtalloc1_fib .
-.Pp
-The
-.Fn RTFREE
-macro is used to unref and possibly free an unlocked route entries with
-one our reference, for example previously allocated by
-.Fn rtalloc_fib
-or
-.Fn rtalloc_ign_fib .
-.Pp
-Both
-.Fn RTFREE_LOCKED
-and
-.Fn RTFREE
-macros decrement the reference count on the routing table entry,
-and proceed with actual freeing if the reference count has reached zero.
-.Pp
-The
-.Fn RT_LOCK
-macro is used to lock a routing table entry.
-.Pp
-The
-.Fn RT_UNLOCK
-macro is used to unlock a routing table entry.
-.Pp
-The
-.Fn RT_ADDREF
-macro increments the reference count on a previously locked route entry.
-It should be used whenever a reference to an
-.Xr rtentry 9
-is going to be stored outside the routing table.
-.Pp
-The
-.Fn RT_REMREF
-macro decrements the reference count on a previously locked route entry.
-Its usage is contrary to
-.Fn RT_ADDREF .
-.Pp
-The
-.Fn RO_RTFREE
-macro is used to free route entry that is referenced by struct route.
-At certain circumstances the latter may not hold a reference on rtentry,
-and
-.Fn RO_RTFREE
-treats such routes correctly.
-.Pp
-The
-.Fn rtfree
-function does the actual free of the routing table entry, and shouldn't
-be called directly by facilities, that just perform routing table lookups.
-.Sh LEGACY INTERFACE
-Prior to introduction of multiple routing tables functions did not
-require the
-.Fa "u_int fibnum"
-argument.
-Legacy
-.Fn rtalloc1 ,
-.Fn rtalloc
-and
-.Fn rtalloc_ign
-functions are kept for compatibility, and are equivalent to
-calling new interface with
-.Fa fibnum
-argument equal to
-.Va 0 ,
-which implies default forwarding table.
-.Sh RETURN VALUES
-The
-.Fn rtalloc1_fib
-function returns a pointer to a locked routing-table entry if it succeeds,
-otherwise a null pointer.
-The
-.Fn rtalloc_fib
-and
-.Fn rtalloc_ign_fib
-functions do not return a value, but they fill in the
-.Fa *ro_rt
-member of the
-.Fa *ro
-argument with a pointer to an unlocked routing-table entry if they
-succeed, otherwise a null pointer.
-In a case of success all functions put a reference on the
-routing-table entry, freeing of which is responsibility of the caller.
-Lack of a route should in most cases be
-translated to the
-.Xr errno 2
-value
-.Er EHOSTUNREACH .
-.Sh SEE ALSO
-.Xr route 4 ,
-.Xr rtentry 9
-.Sh HISTORY
-The
-.Nm rtalloc
-facility first appeared in
-.Bx 4.2 ,
-although with much different internals.
-The
-.Fn rtalloc_ign
-function and the
-.Fa flags
-argument to
-.Fn rtalloc1
-first appeared in
-.Fx 2.0 .
-Routing table locking was introduced in
-.Fx 5.2 .
-Multiple routing tables were introduced in
-.Fx 8.0 .
