Yes, it would be SPI interface to the DataFlash. It would not be a 'direct' interface (sorry for the confusion) - the TCP handler would require rewrite/additional code such that if it was passed a DataFlash address, it would appropriately retrieve the data from DataFlash as needed. I'm sure it could be done, but most likely a big code change and it seems no gain for the trouble. > Actually I think this will not improve the performance of MAC.
