Self-Reception Scheme in the Native CAN Driver

Modify the kernel/arch/arm64/boot/dts/rockchip/rk3568.dtsi file, comment out the following figure, and cancel the configuration of the workround frame. After modification, the TXtoRX of the CAN will be opened automatically. When the original CAN sends the extended frame data, It will take back the data sent by itself for verification. If the verification is not an extended frame, it will send a new frame.

Note: This scheme may trigger an infinite retransmission mechanism when the extended part of the ID contains zeros (e.g., specific IDs with zero extensions). Use with caution.
