通过 can socket编程的时候收到的can 帧是一个 can_frame的结构。想问下这个结构中的can_id对应到TMS570LS3137de DCAN口中是哪个值？
/**
* struct can_frame - basic CAN frame structure
* @can_id: CAN ID of the frame and CAN_*_FLAG flags, see canid_t definition
* @can_dlc: frame payload length in byte (0 .. 8) aka data length code
* N.B. the DLC field from ISO 11898-1 Chapter 8.4.2.3 has a 1:1
* mapping of the 'data length code' to the real payload length
* @data: CAN frame payload (up to 8 byte)
*/
struct can_frame {
canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */
__u8 can_dlc; /* frame payload length in byte (0 .. CAN_MAX_DLEN) */
__u8 data[CAN_MAX_DLEN] __attribute__((aligned(8)));
};
