The script also changes the parameter 'arg' to 'dev' when relevant.

Move the can_set_bitrate() function to can_common.c as it is getting

Only call the state change callback if the state has changed. Reuse the

According to Kconfig guidelines, boolean prompts must not start with
"Enable...". The following command has been used to automate the changes
in this patch:

Add CAN controller device statistics support.
Initially the following per-device statistics are supported:
- Dominant bit transmission errors
- Recessive bit transmission errors
- Bit stuffing errors
- CRC errors
- Format errors
- Acknowledge errors

Reduce the number of TX buffers in use on the MCP2515 from 3 to 1 in
order to avoid CAN frame priority inversion.
The MCP2515 is unable to do internal TX frame arbitration based on the
CAN-ID of the frame. Priority must be set per TX buffer and the priority
cannot be rewritten unless the frame transmission is aborted.

The CAN_BUS_UNKNOWN CAN controller state is only used to indicate that
the current CAN controller state could not be read.
Remove it and change the signature of the can_get_state() API function
to return an integer indicating success or failure.

Rework the transmit error handling in the NXP MCUX FlexCAN driver:
- Frame transmission must be automatically retried in case of lost
arbitration or missing acknowledge.
- Abort any pending TX frames when bus-off state is entered.
- Fail early in can_send() if in bus-off state.
