| 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. |
