It uses a fixed packet size and is + connection oriented, allowing for the negotiation of minimum + bandwidth requirements. + + In order to participate in an ATM network, your Linux box needs an + ATM networking card. If you have that, say Y here and to the driver + of your ATM card below. + + Note that you need a set of user-space programs to actually make use + of ATM. See the file <file:Documentation/networking/atm.txt> for + further details. + +config ATM_CLIP + tristate "Classical IP over ATM (EXPERIMENTAL)" + depends on ATM && INET + help + Classical IP over ATM for PVCs and SVCs, supporting InARP and + ATMARP. If you want to communication with other IP hosts on your ATM + network, you will typically either say Y here or to "LAN Emulation + (LANE)" below. + +config ATM_CLIP_NO_ICMP + bool "Do NOT send ICMP if no neighbour (EXPERIMENTAL)" + depends on ATM_CLIP + help + Normally, an "ICMP host unreachable" message is sent if a neighbour + cannot be reached because there is no VC to it in the kernel's + ATMARP table. This may cause problems when ATMARP table entries are + briefly removed during revalidation. If you say Y here, packets to + such neighbours are silently discarded instead. + +config ATM_LANE + tristate "LAN Emulation (LANE) support (EXPERIMENTAL)" + depends on ATM + help + LAN Emulation emulates services of existing LANs across an ATM + network. Besides operating as a normal ATM end station client, Linux + LANE client can also act as an proxy client bridging packets between + ELAN and Ethernet segments. You need LANE if you want to try MPOA. + +config ATM_MPOA + tristate "Multi-Protocol Over ATM (MPOA) support (EXPERIMENTAL)" + depends on ATM && INET && ATM_LANE!=n + help + Multi-Protocol Over ATM allows ATM edge devices such as routers, + bridges and ATM attached hosts establish direct ATM VCs across + subnetwork boundaries. These shortcut connections bypass routers + enhancing overall network performance. + +config ATM_BR2684 + tristate "RFC1483/2684 Bridged protocols" + depends on ATM && INET + help + ATM PVCs can carry ethernet PDUs according to rfc2684 (formerly 1483) + This device will act like an ethernet from the kernels point of view, + with the traffic being carried by ATM PVCs (currently 1 PVC/device). + This is sometimes used over DSL lines.
