/**
* @file IxEthMii.h
*
* @brief this file contains the public API of @ref IxEthMii component
*
* Design notes :
* The main intent of this API is to inplement MII high level fonctionalitoes
* to support the codelets provided with the IXP400 software releases. It
* superceedes previous interfaces provided with @ref IxEThAcc component.
*
* This API has been tested with the PHYs provided with the
* IXP400 development platforms. It may not work for specific Ethernet PHYs
* used on specific boards.
*
* This source code detects and interface the LXT972, LXT973 and KS6995
* Ethernet PHYs.
*
* This source code should be considered as an example which may need
* to be adapted for different hardware implementations.
*
* It is strongly recommended to use public domain and GPL utilities
* like libmii, mii-diag for MII interface support.
*
*
*
* @par
* IXP400 SW Release version 2.0
