1.4.1.1. MAC
The MAC transmit block adds the PHY transmit path delay to the timestamp, places the net timestamp value at the byte offset given by the packet parser and recalculates the CRC for the packet before the packet is sent to the PHY. The 1588 MAC receive block record the timestamp of the incoming packet, subtracts the PHY receive path delay from the timestamp and sends the net timestamp value to the user logic.
