6	tristate "Asynchronous Transfer Mode (ATM)"
7	---help---
8	  ATM is a high-speed networking technology for Local Area Networks
9	  and Wide Area Networks.  It uses a fixed packet size and is
10	  connection oriented, allowing for the negotiation of minimum
11	  bandwidth requirements.
12
13	  In order to participate in an ATM network, your Linux box needs an
14	  ATM networking card. If you have that, say Y here and to the driver
15	  of your ATM card below.
16
17	  Note that you need a set of user-space programs to actually make use
18	  of ATM.  See the file <file:Documentation/networking/atm.txt> for
19	  further details.

21config ATM_CLIP
22	tristate "Classical IP over ATM"
23	depends on ATM && INET
24	help
25	  Classical IP over ATM for PVCs and SVCs, supporting InARP and
26	  ATMARP. If you want to communication with other IP hosts on your ATM
27	  network, you will typically either say Y here or to "LAN Emulation
28	  (LANE)" below.
29
30config ATM_CLIP_NO_ICMP
31	bool "Do NOT send ICMP if no neighbour"
32	depends on ATM_CLIP
33	help
34	  Normally, an "ICMP host unreachable" message is sent if a neighbour
35	  cannot be reached because there is no VC to it in the kernel's
36	  ATMARP table. This may cause problems when ATMARP table entries are
37	  briefly removed during revalidation. If you say Y here, packets to
38	  such neighbours are silently discarded instead.

40config ATM_LANE
41	tristate "LAN Emulation (LANE) support"
42	depends on ATM
43	help
44	  LAN Emulation emulates services of existing LANs across an ATM
45	  network. Besides operating as a normal ATM end station client, Linux
46	  LANE client can also act as an proxy client bridging packets between
47	  ELAN and Ethernet segments. You need LANE if you want to try MPOA.
48
49config ATM_MPOA
50	tristate "Multi-Protocol Over ATM (MPOA) support"
51	depends on ATM && INET && ATM_LANE!=n
52	help
53	  Multi-Protocol Over ATM allows ATM edge devices such as routers,
54	  bridges and ATM attached hosts establish direct ATM VCs across
55	  subnetwork boundaries. These shortcut connections bypass routers
56	  enhancing overall network performance.
57
58config ATM_BR2684
59	tristate "RFC1483/2684 Bridged protocols"
60	depends on ATM && INET
61	help
62	  ATM PVCs can carry ethernet PDUs according to RFC2684 (formerly 1483)
63	  This device will act like an ethernet from the kernels point of view,
64	  with the traffic being carried by ATM PVCs (currently 1 PVC/device).
65	  This is sometimes used over DSL lines.  If in doubt, say N.
66
67config ATM_BR2684_IPFILTER
68	bool "Per-VC IP filter kludge"
69	depends on ATM_BR2684
70	help
71	  This is an experimental mechanism for users who need to terminate a
72	  large number of IP-only vcc's.  Do not enable this unless you are sure
73	  you know what you are doing.
