CAN network state of art

[demoa00]

I want to know the state of the implementation of the CAN network for the configuration rpi4 with Android Automotive OS 14. In the aosp_rpi4_car.mk there is a section about the CAN network to include its functionalities, from the system log I see that the CanController start but I don't see any interface for the CAN (e.g. can0) when in the ADB shell i use the command ip link show. There are some other changes to do in order to make up the CAN network? Sorry in advance if I wrote in the wrong place. Thanks.
