1# 2# Asynchronous Transfer Mode (ATM) 3# 4 5config ATM 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. 20 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. 39 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. 74
