+ *
+ * @defgroup IxAtmdAccAPI IXP400 ATM Driver Access (IxAtmdAcc) API
+ *
+ * @brief The public API for the IXP400 Atm Driver Data component
+ *
+ * IxAtmdAcc is the low level interface by which AAL0/AAL5 and
+ * OAM data gets transmitted to,and received from the Utopia bus.
+ *
+ * For AAL0/AAL5 services transmit and receive connections may
+ * be established independantly for unique combinations of
+ * port,VPI,and VCI.
+ *
+ * Two AAL0 services supporting 48 or 52 byte cell data are provided.
+ * Submitted AAL0 PDUs must be a multiple of the cell data size (48/52).
+ * AAL0_52 is a raw cell service the client must format
+ * the PDU with an ATM cell header (excluding HEC) at the start of
+ * each cell, note that AtmdAcc does not validate the cell headers in
+ * a submitted PDU.
+ *
+ * OAM cells cannot be received over the AAL0 service but instead
+ * are received over a dedicated OAM service.
+ *
+ * For the OAM service an "OAM Tx channel" may be enabled for a port
+ * by establishing a single dedicated OAM Tx connection on that port.
+ * A single "OAM Rx channel" for all ports may be enabled by
+ * establishing a dedicated OAM Rx connection.
+ *
+ * The OAM service allows buffers containing 52 byte OAM F4/F5 cells
+ * to be transmitted and received over the dedicated OAM channels.
+ * HEC is appended/removed, and CRC-10 performed by the NPE. The OAM
+ * service offered by AtmdAcc is a raw cell transport service.
+ * It is assumed that ITU I.610 procedures that make use of this
+ * service are implemented above AtmdAcc.
+ *
+ * Note that the dedicated OAM connections are established on
+ * reserved VPI,VCI, and (in the case of Rx) port values defined below.
+ * These values are used purely to descriminate the dedicated OAM channels
+ * and do not identify a particular OAM F4/F5 flow. F4/F5 flows may be
+ * realised for particluar VPI/VCIs by manipulating the VPI,VCI
+ * fields of the ATM cell headers of cells in the buffers passed
+ * to AtmdAcc. Note that AtmdAcc does not validate the cell headers
+ * in a submitted OAM PDU.

+ *
+ * @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.
+ *

+ * @defgroup IxHssAccAPI IXP400 HSS Access (IxHssAcc) API
+ *
+ * @brief The public API for the IXP400 HssAccess component
+ *
+ * IxHssAcc is the access layer to the HSS packetised and channelised
+ * services
+ *
+ * <b> Design Notes </b><br>
+ * <UL>
+ * <LI>When a packet-pipe is configured for 56Kbps RAW mode, byte alignment of
+ * the transmitted data is not preserved. All raw data that is transmitted
+ * will be received in proper order by the receiver, but the first bit of
+ * the packet may be seen at any offset within a byte; all subsequent bytes
+ * will have the same offset for the duration of the packet. The same offset
+ * also applies to all subsequent packets received on the packet-pipe too.
+ * (Similar results will occur for data received from remote end.) While
+ * this behavior will also occur for 56Kbps HDLC mode, the HDLC
+ * encoding/decoding will preserve the original byte alignment at the
+ * receiver end.
+ * </UL>
+ *
+ * <b> 56Kbps Packetised Service Bandwidth Limitation </b><br>
+ * <UL>
+ * <LI>IxHssAcc supports 56Kbps packetised service at a maximum aggregate rate
+ * for all HSS ports/HDLC channels of 12.288Mbps[1] in each direction, i.e.
+ * it supports 56Kbps packetised service on up to 8 T1 trunks. It does
+ * not support 56Kbps packetised service on 8 E1 trunks (i.e. 4 trunks per
+ * HSS port) unless those trunks are running 'fractional E1' with maximum
+ * aggregate rate of 12.288 Mbps in each direction.<br>
+ * [1] 12.288Mbps = 1.536Mbp * 8 T1

+ * This module contains the implementation of the OS Services buffer pool
+ * management service. This module provides routines for creating pools
+ * of buffers for exchange of network data, getting and returning buffers
+ * from and to the pool, and some other utility functions.
+ * <P>
+ * Currently, the pool has 2 underlying implementations - one for the vxWorks
+ * OS, and another which attempts to be OS-agnostic so that it can be used on
+ * other OS's such as Linux. The API is largely the same for all OS's,
+ * but there are some differences to be aware of. These are documented
+ * in the API descriptions below.
+ * <P>
+ * The most significant difference is this: when this module is used with
+ * the WindRiver VxWorks OS, it will create a pool of vxWorks "MBufs".
+ * These can be used directly with the vxWorks "netBufLib" OS Library.
+ * For other OS's, it will create a pool of generic buffers. These may need
+ * to be converted into other buffer types (sk_buff's in Linux, for example)
+ * before being used with any built-in OS routines available for
+ * manipulating network data buffers.

+ * @file IxQMgr.h
+ *
+ * @date 30-Oct-2001
+ *
+ * @brief This file contains the public API of IxQMgr component.
+ *
+ * Some functions contained in this module are inline to achieve better
+ * data-path performance. For this to work, the function definitions are
+ * contained in this header file. The "normal" use of inline functions
+ * is to use the inline functions in the module in which they are
+ * defined. In this case these inline functions are used in external
+ * modules and therefore the use of "inline extern". What this means
+ * is as follows: if a function foo is declared as "inline extern" this
+ * definition is only used for inlining, in no case is the function
+ * compiled on its own. If the compiler cannot inline the function it
+ * becomes an external reference. Therefore in IxQMgrQAccess.c all
+ * inline functions are defined without the "inline extern" specifier
+ * and so define the external references. In all other source files
+ * including this header file, these funtions are defined as "inline
+ * extern".

+ * @file IxQMgrAqmIf_p.h
+ *
+ * @author Intel Corporation
+ * @date 30-Oct-2001
+ *
+ * @brief The IxQMgrAqmIf sub-component provides a number of inline
+ * functions for performing I/O on the AQM.
+ *
+ * Because some functions contained in this module are inline and are
+ * used in other modules (within the QMgr component) the definitions are
+ * contained in this header file. The "normal" use of inline functions
+ * is to use the inline functions in the module in which they are
+ * defined. In this case these inline functions are used in external
+ * modules and therefore the use of "inline extern". What this means
+ * is as follows: if a function foo is declared as "inline extern"this
+ * definition is only used for inlining, in no case is the function
+ * compiled on its own. If the compiler cannot inline the function it
+ * becomes an external reference. Therefore in IxQMgrAqmIf.c all
+ * inline functions are defined without the "inline extern" specifier
+ * and so define the external references. In all other modules these
+ * funtions are defined as "inline extern".

+ * The timer callback control component provides a mechanism by which different
+ * client components can start a timer and have a supplied callback function
+ * invoked when the timer expires.
+ * The callbacks are all dispatched from one thread inside this component.
+ * Any component that needs to be called periodically should use this facility
+ * rather than create its own task with a sleep loop.

+ *
+ * = DESCRIPTION
+ * This file contains the prototypes of OS-independent wrapper
+ * functions which allow the programmer not to be tied to a specific
+ * operating system. The OSSL functions can be divided into three classes:
+ *
+ * 1) synchronization-related wrapper functions around thread system calls
+ * 2) thread-related wrapper functions around thread calls
+ * 3) transactor/workbench osapi calls -- defined in osApi.h
+ *
+ * Both 1 and 2 classes of functions provide Thread Management, Thread
+ * Synchronization, Mutual Exclusion and Timer primitives. Namely,
+ * creation and deletion functions as well as the standard "wait" and
+ * "exit". Additionally, a couple of utility functions which enable to
+ * pause the execution of a thread are also provided.
+ *
+ * The 3rd class provides a slew of other OSAPI functions to handle
+ * Transactor/WorkBench OS calls.
+ *
+ *
+ * OSSL Thread APIs:
+ * The OSSL thread functions that allow for thread creation,
+ * get thread id, thread deletion and set thread priroity.
