 the xCORE device. The RMII layer receives packets of data which are
 then routed by an Ethernet MAC layer to multiple processes running on
 the xCORE. SMI provides the management interface between the PHY and

 The application communicates with the Ethernet MAC that drives the RMII
 data interface to the PHY. A separate PHY driver configures the PHY
