- Add IXP4xx NPE ethernet MAC support
- Add support for Intel IXDPG425 board
- Add support for Prodrive PDNB3 board
- Add IRQ support
Patch by Stefan Roese, 23 May 2006

[This patch does not include cpu/ixp/npe/IxNpeMicrocode.c which still
 sufferes from licensing issues. Blame Intel.]

* @brief Header file for the IXP400 ATM Traffic Shaper
*
* This component demonstrates an ATM Traffic Shaper implementation. It
* will perform shaping on upto 12 ports and total of 44 VCs accross all ports,
* 32 are intended for AAL0/5 and 12 for OAM (1 per port).
* The supported traffic types are;1 rt-VBR VC where PCR = SCR.
* (Effectively CBR) and Up-to 44 VBR VCs.
*
* This component models the ATM ports and VCs and is capable of producing
* a schedule of ATM cells per port which can be supplied to IxAtmdAcc
* for execution on the data path.

*
* @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.
*
*

*
* If in interrupt mode and IxI2cMasterReadCallbackP is NULL, then the driver will
* wait for the operation to complete, and then return.
*
* And if the repeated start transfer mode is selected, then it will not send a
* stop signal at the end of all the transfers.
* *NOTE*: If repeated start transfer mode is selected, it has to end with a
* normal mode transfer mode else the bus will continue to be held
