1. A system for providing an enhanced acknowledgement (ENH-ACK) frame, the system configured to:
receive an incoming packet transmitted by an external device;
determine that an ENH-ACK response is required based on a MAC header of the incoming packet;
schedule transmission of the ENH-ACK frame to the external device in accordance with a standard turnaround time limit relative to receipt of the incoming packet;
determine contents of one or more packet processed fields of the ENH-ACK frame and populate the one or more packet processed fields; and
complete transmission of the ENH-ACK frame with the populated packet processed fields,
wherein the system is configured to determine the contents of the one or more packet processed fields as:
calculated values of the one or more packet processed fields if system software determines the calculated values prior to expiry of a corresponding calculation deadline; or
fallback values if the system software fails to determine the calculated values of the one or more packet processed fields prior to expiry of the corresponding calculation deadline,
wherein the one or more calculation deadlines comprise a frame length calculation deadline and a payload calculation deadline.
