Abstract: A media access control (MAC) processor of a network device receives a timing packet to be transmitted by the network device. The MAC processor generates one or more indicators to be used by a PHY device of the network device for embedding timing information into the timing packet. The one or more indicators include at least an indicator indicating that the timing packet is a type of packet into which timing information is to be embedded, an indicator of a location of a field in the timing packet at which the timing information is to be embedded, and an indicator of whether timing information in the timing packet needs to be updated. The MAC processor transfers the timing packet and the one or more indicators to the PHY device for further processing of the timing packet and subsequent transmission of the timing packet from the network device.
