-Used by
-.Xr pf 4
-to tag packets based on their purpose/behavior.
-Packets could be generated by the packet filter cached as
-fragmented, marked for queueing, or redirected to localhost.
-Packets generated, routed, or stored due to fragmentation
-by the packet filter contain no data.
-When generated by

-they are not tested and thus passed unconditionally.

-In order to prevent loops caused by subsequent matching
-routing rules, packets routed by
-.Xr pf 4
-are not tested more than once.
-.Pp
-Packets that have been cached by the fragment cache will do
-a short circuit if processed again.
-If they were to re-enter the fragcache,
-they would be indistinguishable from a
-duplicate of a previous packet and would be dropped.
-.Pp
-When queueing happens the tag will contain the ID of the
-queue this packet should go to.

-Another scenario takes place when TCP and UDP packets are to
-be redirected to loopback addresses.
-The functions tcp_input() and udp_input() reverse the order of
-lookups in in_pcblookup_listen(), when this tag is present, so
-unspecific listeners are matched before specific ones.
-This prevents external connections from appearing local to daemons
-such as
-.Xr portmap 8
-listening on both unspecific and specific loopback sockets in order to
-grant higher privileges to local users.
