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

31 | tristate "Broadcast Manager CAN Protocol (with content filtering)" | |
32 | depends on CAN | |
33 | default N | |
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. | |
