Включил в ядро поддержку CAN интерфейса. Как это теперь настроить. И что вообще надо сделать, что бы из своей проги читать и писать в CAN сеть.

To set CAN device properties:
ip link set can0 type can

To display CAN device details and statistics:
ip -details -statistics link show can0

To set the CAN bit-timing:
CAN bit-timing parameters can always be defined in a hardware independent format as
proposed in the CAN 2.0 specification specifying the arguments `tq`, `prop_seg`,
`phase_seg1`, `phase_seg2` and `sjw`:
ip link set can0 type can tq 125 prop-seg 6 phase-seg1 7 phase-seg2 2 sjw 1

To set the CAN device bit-rate:
ip link set can0 type can bitrate 125000
Starting and stopping a device using Netlink interface

To start a CAN network device:
ip link set can0 up
OR
ifconfig can0 up

To stop a CAN network device:
ip link set can0 down
OR
ifconfig can0 down
