[yocto] SocketCan support for Yocto

[Rudolf Streif]

Subbu,

You need to enable the CAN subsystem in the Linux kernel:

CONFIG_CAN=y (or m if you prefer a module)

CONFIG_NET=y must be enabled for this (but is by default).


You did not specify if you are using a particular CAN hardware that
supports socket CAN. If so you need to enable the driver for that too. For
example, a popular one is USB Peak CAN: CONFIG_CAN_PEAK_USB.

Or if you want to use a virtual CAN interface CONFIG_CAN_VCAN=y


You can change kernel configuration parameters for testing with:

bitbake -c menuconfig virtual/kernel

which will open the menu configuration for the kernel your Yocto build is
using.
