Data Fields
uint32_t	polls
uint32_t	replies
uint32_t	timeouts
uint32_t	mismatches
uint32_t	nacks
uint32_t	rx_crc_errors
uint32_t	rx_resyncs
bool	have_status
uint32_t	dev_frames
uint32_t	dev_crc_errors
	The IOmcu's CAN receive error counter (REC, 0 to 255) at the status read: it rises with bad frames and falls with good ones, a level rather than a count.
uint32_t	dev_resyncs
	The IOmcu's CAN transmit error counter (TEC, 0 to 255), a level as dev_crc_errors.
bool	have_refused
	The last status read carried LINK_ST_REFUSED_LO and _HI: protocol 4.21 and later.
uint32_t	dev_refused
	CAN frames it refused to decode since its power-up, modulo 2^32; 0 while have_refused is false.
bool	have_identity
uint16_t	proto_major
uint16_t	proto_minor
uint32_t	rt_samples
uint32_t	rt_min_us
uint32_t	rt_max_us
uint32_t	rt_mean_us
