38 node type translates frames in to and out of ATM LLC encapsulation,
39 as specified by RFC 1483.
40 In LLC encapsulation the protocol of a given protocol data unit (PDU) is
41 specified by an IEEE 802.2 LLC header, possibly followed by an IEEE 802.1a
42 SubNetwork Attachment Point (SNAP) header.
43 This node currently handles the Ethernet and FDDI protocols.
45 The node transmits and receives ATM PDUs on the
48 Received PDUs are decoded and forwarded to the
57 hooks are assumed to be full Ethernet or FDDI packets as appropriate and are
58 encapsulated into a PDU and transmitted via the
62 This node type supports the following hooks:
63 .Bl -tag -width ".Va ether"
66 Typically, this hook would be connected to a
68 node, which handles transmission of ATM PDUs over an ATM device.
71 This hook sends and receives Ethernet frames.
72 This would normally be connected to an
77 This hook sends and receives FDDI frames.
80 This node type supports the generic control messages.
82 This node shuts down upon receipt of a
84 control message, or when all hooks have been disconnected.
