Hardware time stamping is used because it provides better accuracy by time stamping packets at the exact moment they are sent and received. Hardware time stamping requires hardware PTP support from the PHY/MAC. passion for fashion bootsWebbboundary clock use the inband mechanisms of timestamp transfer when possible. Enable timestamp insertion for receive PTP event messages. This eliminates the need to read the receive timestamp over MDIO. It also eliminates issues with matching timestamps to packets since the timestamp arrives embedded in the packet. tin of milo
