38.3.2 IXXAT IOCTL Commands Defines
Command: PTP_GET_TX_TIME
Description: command provides the timestamp of the transmit packet with specific PTP
sequence ID and returns the timestamp, the sender port-ID, the PTP version, and the
message type through the ptp_ts_data structure.
Command: PTP_GET_RX_TIME
Description: command provides the timestamp of the receive packet with specific PTP
sequence ID and returns the timestamp, the sender port-ID, the PTP version, and the
message type, through the ptp_ts_data structure.
