patches. Protocol numbers are already in include/linux/can.h.

+ 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.
