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

  26           Classical IP over ATM for PVCs and SVCs, supporting InARP and
  27           ATMARP. If you want to communication with other IP hosts on your ATM
  28           network, you will typically either say Y here or to "LAN Emulation
  29           (LANE)" below.

  34         help
  35           Normally, an "ICMP host unreachable" message is sent if a neighbour
  36           cannot be reached because there is no VC to it in the kernel's
  37           ATMARP table. This may cause problems when ATMARP table entries are
  38           briefly removed during revalidation. If you say Y here, packets to
  39           such neighbours are silently discarded instead.

  45           LAN Emulation emulates services of existing LANs across an ATM
  46           network. Besides operating as a normal ATM end station client, Linux
  47           LANE client can also act as an proxy client bridging packets between
  48           ELAN and Ethernet segments. You need LANE if you want to try MPOA.

  54           Multi-Protocol Over ATM allows ATM edge devices such as routers,
  55           bridges and ATM attached hosts establish direct ATM VCs across
  56           subnetwork boundaries. These shortcut connections bypass routers
  57           enhancing overall network performance.

  63           ATM PVCs can carry ethernet PDUs according to RFC2684 (formerly 1483)
  64           This device will act like an ethernet from the kernels point of view,
  65           with the traffic being carried by ATM PVCs (currently 1 PVC/device).
  66           This is sometimes used over DSL lines.  If in doubt, say N.

  72           This is an experimental mechanism for users who need to terminate a
  73           large number of IP-only vcc's.  Do not enable this unless you are sure
  74           you know what you are doing.
