+RFC1483/2684 Bridged protocols
+CONFIG_ATM_BR2684
+  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.

+Per-VC IP filter kludge
+CONFIG_ATM_BR2684_IPFILTER
+  This is an experimental mechanism for users who need to terminating a
+  large number of IP-only vcc's.  Do not enable this unless you are sure
+  you know what you are doing.
