Software can use the SA insertion or replacement feature to instruct the MAC to do the following for transmit frames:
The software can enable the SA insertion or replacement for all transmitted frames or selective frames:
When SA insertion is enabled, the application should ensure that the frames that are sent to the MAC do not have the SA field. The MAC does not check the presence of SA field in the transmit frame and just inserts the content of MAC Address Registers in the SA field. Similarly, when SA replacement is enabled, the application should ensure that the frames that are sent to the MAC have the SA field. The MAC just replaces the six bytes, following the Destination Address field in the transmit frame, with the content of the MAC Address Registers.
