During the development of CAN XL, we found the need of creating a dummy CAN XL driver in order to test the new netlink interface. While this code was initially intended to be some throwaway, it received some positive feedback. Add the dummy_can driver. This driver acts similarly to the vcan interface in the sense that it will echo back any packet it receives. The difference is that it exposes a set on bittiming parameters as a real device would and thus must be configured as if it was a real physical interface. The driver comes with a debug mode. If debug message are enabled (for example by enabling CONFIG_CAN_DEBUG_DEVICES), it will print in the kernel log all the bittiming values, similar to what a: ip --details link show can0 would do. This driver is mostly intended for debugging and testing, but some developers also may want to look at it as a simple reference implementation.
