Test Classic (Non-FD) CAN

First, configure both the CAN interfaces with required bitrates:

# sudo ip link set can0 type can bitrate 500000 berr-reporting on && sudo ip link set up can0
# sudo ip link set can1 type can bitrate 500000 berr-reporting on && sudo ip link set up can1

Open a new ssh terminal and run the following commands to receive CAN packets sent by can0 interface.
```
# candump -x can0 &
```
On another terminal, run the following to send one CAN packet via the can0 interface, where 220 is the CAN ID and 50 is data bytes.
```
# cansend can0 220#50
```
The CAN packet sent by cansend is received on candump terminal.
