+.Sh NAME
+.Nm ng_atmllc
+.Nd ATM LLC netgraph node type
+.Sh SYNOPSIS
+.In netgraph/ng_atmllc.h
+.Sh DESCRIPTION
+The
+.Nm atmllc
+node type translates frames in to and out of ATM LLC encapsulation,
+as specified by RFC 1483.
+In LLC encapsulation the protocol of a given protocol data unit (PDU) is
+specified by an IEEE 802.2 LLC header, possibly followed by an IEEE 802.1a
+SubNetwork Attachment Point (SNAP) header.
+This node currently handles the Ethernet and FDDI protocols.
+.Pp
+The node transmits and receives ATM PDUs on the
+.Va atm
+hook.
+Received PDUs are decoded and forwarded to the
+.Va ether
+or
+.Va fddi
+hooks as appropriate.
+Data received on the
+.Va ether
+or
+.Va fddi
+hooks are assumed to be full Ethernet or FDDI packets as appropriate and are
+encapsulated into a PDU and transmitted via the
+.Va atm
+hook.
+.Sh HOOKS
+This node type supports the following hooks:
+.Bl -tag -width indent
+.It Va atm
+ATM connection.
+Typically, this hook would be connected to a
+.Xr ng_atm 4
+node, which handles transmission of ATM PDUs over an ATM device.
+.It Va ether
+Ethernet connection.
+This hook sends and receives Ethernet frames.
+This would normally be connected to an
+.Xr ng_eiface 4
+node if in use.
+.It Va fddi
+FDDI connection.
+This hook sends and receives FDDI frames.
+.El
+.Sh CONTROL MESSAGES
+This node type supports the generic control messages.
+.Sh SHUTDOWN
+This node shuts down upon receipt of a
+.Dv NGM_SHUTDOWN
+control message, or when all hooks have been disconnected.
