tristate "CAN bus subsystem support" |
|
---help--- |
|
Controller Area Network (CAN) is a slow (up to 1Mbit/s) serial |
|
communications protocol which was developed by Bosch in |
|
1991, mainly for automotive, but now widely used in marine |
|
(NMEA2000), industrial, and medical applications. |
|
More information on the CAN network protocol family PF_CAN |
|
is contained in <Documentation/networking/can.txt>. |
|
|
|
If you want CAN support you should say Y here and also to the |
|
specific driver for your controller(s) below. |

tristate "Raw CAN Protocol (raw access with CAN-ID filtering)" |
|
default y |
|
---help--- |
|
The raw CAN protocol option offers access to the CAN bus via |
|
the BSD socket API. You probably want to use the raw socket in |
|
most cases where no higher level protocol is being used. The raw |
|
socket has several filter options e.g. ID masking / error frames. |
|
To receive/send raw CAN messages, use AF_CAN with protocol CAN_RAW. |
|
|
|
config CAN_BCM |
|
tristate "Broadcast Manager CAN Protocol (with content filtering)" |
|
default y |
|
---help--- |
|
The Broadcast Manager offers content filtering, timeout monitoring, |
|
sending of RTR frames, and cyclic CAN messages without permanent user |
|
interaction. The BCM can be 'programmed' via the BSD socket API and |
|
informs you on demand e.g. only on content updates / timeouts. |
|
You probably want to use the bcm socket in most cases where cyclic |
|
CAN messages are used on the bus (e.g. in automotive environments). |
|
To use the Broadcast Manager, use AF_CAN with protocol CAN_BCM. |

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