PROCESSOR-SDK-AM437X: How to configure CAN using "ip" command

	//Create an empty socket API with
	//PF_CAN as the protocol family
	int s;

	cout << "Creating the socket: " << endl;
	if ((s = socket(PF_CAN, SOCK_RAW, CAN_RAW)) < 0)
	{
		result = SOCKET_ERROR;
		return result;
	}
	cout << "Done.     Socket fd: " << s << endl << endl;

	//----------------------------------------
	//----------------------------------------
	//Bind the socket to one of the interfaces
	struct sockaddr_can addr;
	struct ifreq ifr;
	strcpy(ifr.ifr_name, (const char*)"can0");

	ioctl(s, SIOCGIFINDEX, &ifr);

	//memset(&addr, 0, sizeof(addr));
	addr.can_family = AF_CAN;
	addr.can_ifindex = ifr.ifr_ifindex;

	cout << "Binding to addr: " << endl;
	if (bind(s, (struct sockaddr *)&addr, sizeof(addr)) < 0)
	{
		return SOCKET_ERROR;
	}
	cout << "Done" << endl << endl;

	//Writing CAN frames: To send a frame with the
	//ID 0x101 and a two byte payload of 0x41, 0x42

	struct can_frame frame;
	frame.can_id  = 0x555;
	frame.can_dlc = 2;
	frame.data[0] = 0x41;
	frame.data[1] = 0x42;

	cout << "Writing 2 bytes to the socket: " << endl;
	int nBytes = write(s, &frame, sizeof(struct can_frame));

	cout << "wrote " << nBytes << " bytes." << endl;
	if (nBytes != sizeof(struct can_frame))
	{
		cout << "Failed" << endl;
		return DATA_TRANSFER_ERROR;
	}
