| 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.txt> 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. |

| 31 | config ATM_CLIP_NO_ICMP |
| 32 | bool "Do NOT send ICMP if no neighbour (EXPERIMENTAL)" |
| 33 | depends on ATM_CLIP |
| 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. |

| 41 | config ATM_LANE |

| 43 | depends on ATM |
| 44 | help |
| 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. |

| 52 | depends on ATM && INET && ATM_LANE!=n |
| 53 | help |
| 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. |

| 65 | with the traffic being carried by ATM PVCs (currently 1 PVC/device). |
