This patch adds the virtual CAN bus (vcan) network driver. The vcan device is just a loopback device for CAN frames, no real CAN hardware is involved.

|
|
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.

---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)"
|
|
depends on CAN
|
|
default N
|
|
---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.
