10 Controller Area Network (CAN) is a slow (up to 1Mbit/s) serial

11 communications protocol. Development of the CAN bus started in
12 1983 at Robert Bosch GmbH, and the protocol was officially
13 released in 1986. The CAN bus was originally mainly for automotive,
14 but is now widely used in marine (NMEA2000), industrial, and medical
15 applications. More information on the CAN network protocol family
16 PF_CAN is contained in <Documentation/networking/can.rst>.

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

37 The Broadcast Manager offers content filtering, timeout monitoring,
38 sending of RTR frames, and cyclic CAN messages without permanent user
39 interaction. The BCM can be 'programmed' via the BSD socket API and
40 informs you on demand e.g. only on content updates / timeouts.
41 You probably want to use the bcm socket in most cases where cyclic
42 CAN messages are used on the bus (e.g. in automotive environments).
43 To use the Broadcast Manager, use AF_CAN with protocol CAN_BCM.

49 The CAN Gateway/Router is used to route (and modify) CAN frames.
50 It is based on the PF_CAN core infrastructure for msg filtering and
51 msg sending and can optionally modify routed CAN frames on the fly.
52 CAN frames can be routed between CAN network interfaces (one hop).
53 They can be modified with AND/OR/XOR/SET operations as configured
54 by the netlink configuration interface known e.g. from iptables.
