82586 Mode The Destination address Source address and Length field are not used they are placed in
the RX data buffers
32-Bit Segmented and Linear Modes when the Simplified memory model is used the Destination address
Source address and Length fields reside in their respective fields in the RFD When the Flexible memory
strucrture is used the Destination address Source address and Length field locations depend on the SIZE
field of the RFD They can be placed in the RFD in the RX data buffers or partially in the RFD and the rest
in the RX data buffers depending on the SIZE field value
