I have the following questions about the 100Mbps Ethernet controller: 1) This card does DMA from specified memory addresses. How do I know when the DMA completes ? ie, I would actually like to know when I can safely modify the locations from which I'd requested data to be DMA'ed ? 2) What are the total sizes of the transmit and receive buffers on the DC21040 card? Thanks in advance -Chitra Venkatramani (chitra@cs.sunysb.edu)
