Modern Intel systems supports cross timestamping of the network device clock and Always Running Timer (ART) in hardware. This allows the device time and system time to be precisely correlated. The timestamp pair is returned through e1000e_phc_get_syncdevicetime() used by get_system_device_crosststamp(). The hardware cross-timestamp result is made available to applications through the PTP_SYS_OFFSET_PRECISE ioctl which calls e1000e_phc_getcrosststamp().

To verify that your adapter is supported, find the board ID number

on the adapter. Look for a label that has a barcode and a number
|
|
in the format 123456-001 (six digits hyphen three digits).
|
|
|
