	  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.

	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.
