2# Asynchronous Transfer Mode (ATM)
   5config 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.
  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.
  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

  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.
  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.
  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.
  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.
  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.
