Freescale LTIB provides only the low level FlexCAN driver, so you can add Canutils and Libsocketcan developed by Pengutronix to have some more functions available on user space and some test and monitoring applications.

On kernel menuconfig, add the following items:
[*] Networking support ---> <*> CAN bus subsystem support ---> <*> Raw CAN Protocol (raw access with CAN-ID filtering) <*> Broadcast Manager CAN Protocol (with content filtering) CAN Device Drivers ---> <*> Virtual Local CAN Interface (vcan) [*] CAN devices debugging messages <*> Freescale FlexCAN
