33.Os
34.Sh NAME
35.Nm ng_gif_demux
36.Nd demultiplexer for packets from
37.Xr ng_gif 4
38nodes
39.Sh SYNOPSIS
40.In netgraph/ng_gif_demux.h
41.Sh DESCRIPTION
42The
43.Nm
44netgraph node type demultiplexes the output from
45.Xr ng_gif 4
46nodes in the
47.Xr netgraph 4
48networking subsystem.
49.Pp
50The
51.Dv gif
52hook is meant to be connected to the
53.Dv lower
54or
55.Dv orphans
56hook of an
57.Xr ng_gif 4
58node.
59The
60.Dv inet , inet6 , atalk , ipx , atm , natm ,
61and
62.Dv ns
63hooks output frames of the given type when they are received on the
64.Dv gif
65hook.
66When a frame is received on one of these hooks, it is encapsulated and
67sent out the
68.Dv gif
69hook.
70.Sh HOOKS
71This node type supports the following hooks:
72.Bl -tag -width ".Dv inet6"
73.It Va gif
74Connection to the
75.Dv lower
76or
77.Dv orphans
78hook of an
79.Xr ng_gif 4
80node.
81.It Va inet
82Hook for input and output of IP frames.
83.It Va inet6
84Hook for input and output of IPv6 frames.
85.It Va atalk
86Hook for input and output of AppleTalk frames.
87.It Va ipx
88Hook for input and output of IPX frames.
89.It Va atm
90Hook for input and output of ATM frames.
91.It Va natm
92Hook for input and output of NATM frames.
93.It Va ns
94Hook for input and output of NS frames.
95.El
96.Sh CONTROL MESSAGES
97This node type supports only the generic control messages.
