/** * @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 * * -- Copyright Notice -- * * @par * Copyright 2001-2005, Intel Corporation. * All rights reserved. * * @par * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
