+/**
+ * @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.
+ *
