# SPDX-License-Identifier: GPL-2.0-only # # Asynchronous Transfer Mode (ATM) # config ATM tristate "Asynchronous Transfer Mode (ATM)" help ATM is a high-speed networking technology for Local Area Networks and Wide Area Networks. 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.rst> for further details. 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. If in doubt, say N. config ATM_BR2684_IPFILTER bool "Per-VC IP filter kludge" depends on ATM_BR2684 help This is an experimental mechanism for users who need to terminate a large number of IP-only vcc's. Do not enable this unless you are sure you know what you are doing.
