   8         ---help---
   9           Controller Area Network (CAN) is a slow (up to 1Mbit/s) serial
  10           communications protocol which was developed by Bosch in
  11           1991, mainly for automotive, but now widely used in marine
  12           (NMEA2000), industrial, and medical applications.
  13           More information on the CAN network protocol family PF_CAN
  14           is contained in <Documentation/networking/can.txt>.

  16           If you want CAN support you should say Y here and also to the
  17           specific driver for your controller(s) below.

  23         default y
  24         ---help---
  25           The raw CAN protocol option offers access to the CAN bus via
  26           the BSD socket API. You probably want to use the raw socket in
  27           most cases where no higher level protocol is being used. The raw
  28           socket has several filter options e.g. ID masking / error frames.
  29           To receive/send raw CAN messages, use AF_CAN with protocol CAN_RAW.

  31 config CAN_BCM
  32         tristate "Broadcast Manager CAN Protocol (with content filtering)"
  33         default y
  34         ---help---
  35           The Broadcast Manager offers content filtering, timeout monitoring,
  36           sending of RTR frames, and cyclic CAN messages without permanent user
  37           interaction. The BCM can be 'programmed' via the BSD socket API and
  38           informs you on demand e.g. only on content updates / timeouts.
  39           You probably want to use the bcm socket in most cases where cyclic
  40           CAN messages are used on the bus (e.g. in automotive environments).
  41           To use the Broadcast Manager, use AF_CAN with protocol CAN_BCM.
  42
  43 config CAN_GW
  44         tristate "CAN Gateway/Router (with netlink configuration)"
  45         default y
  46         ---help---
  47           The CAN Gateway/Router is used to route (and modify) CAN frames.
  48           It is based on the PF_CAN core infrastructure for msg filtering and
  49           msg sending and can optionally modify routed CAN frames on the fly.
  50           CAN frames can be routed between CAN network interfaces (one hop).
  51           They can be modified with AND/OR/XOR/SET operations as configured
  52           by the netlink configuration interface known e.g. from iptables.
