+/**
+@defgroup Common_Statistics Statistics
+
+A broad array of module statistics is available.  Statistics values are accessed
+through the @c Control() interface of the CPHAL.  There are 5 different levels
+of statistics, each of which correspond to a unique set of data.  Furthermore,
+certain statistics data is indexed by using a channel number and Tx queue number.
+The following is a brief description of each statistics level, along with the
+indexes used for the level:
+
+- Level 0:  Hardware Statistics (index with channel)
+- Level 1:  CPHAL Software Statistics (channel, queue)
+- Level 2:  CPHAL Flags (channel, queue)
+- Level 3:  CPHAL Channel Configuration (channel)
+- Level 4:  CPHAL General Configuration (no index)
+
+The caller requests statistics information by providing a Key string to the
+@c Control() API in the following format: "Stats;[Level #];[Ch #];[Queue #]".
+The only valid Action parameter for statistics usage is "Get".
+
+Code Examples:
+@code
+unsigned int *StatsData;
+
+# Get Level 0 stats for Channel 1
+HalFunc->Control(OsDev->HalDev, "Stats;0;1", "Get", &StatsData);
+
+# Get Level 2 stats for Channel 0, Queue 0
+HalFunc->Control(OsDev->HalDev, "Stats;2;0;0", "Get", &StatsData);
+
+# Get Level 4 stats
+HalFunc->Control(OsDev->HalDev, "Stats;4", "Get", &StatsData);
+@endcode
+
+The information returned in the Value parameter of @c Control() is an
+array of pointers to strings.  The pointers are arranged in pairs.
+The first pointer is a pointer to a name string for a particular statistic.
+The next pointer is a pointer to a string containing the representation of
+the integer statistic value corresponding to the first pointer.  This is followed
+by another pair of pointers, and so on, until a NULL pointer is encountered.  The
+following is example code for processing the statistics data.  Note that the OS
+is responsible for freeing the memory passed back through the Value parameter of
+@c Control().
+
+@code
+unsigned int *StatsData;
+
+# Get Level 0 stats for Channel 1
+HalFunc->Control(OsDev->HalDev, "Stats;0;1", "Get", &StatsData);
+
+# output Statistics data
+PrintStats(StatsData);
+
+# the upper layer is responsible for freeing stats info
+free(&StatsPtr);
+
+...
+
+void PrintStats(unsigned int *StatsPtr)
+  {
+   while(*StatsPtr)
+     {
+      printf("%20s:",  (char *)*StatsPtr);
+      StatsPtr++;
+      printf("%11s\n", (char *)*StatsPtr);
+      StatsPtr++;
+     }
+   MySioFlush();
+  }
+@endcode
+
+Within each statistics level, there are several statistics defined.  The statistics that
+are common to every CPPI module are listed below.  In addition, each module may define
+extra statistics in each level, which will be documented within the module-specific
+documentation appendices.
+
+- Level 0 Statistics
+  - All level 0 statistics are module-specific.
+- Level 1 Statistics (CPHAL Software Statistics)
+  - DmaLenErrors: Incremented when the port DMA's more data than expected (per channel). (AAL5 Only)
+  - TxMisQCnt: Incremented when host queues a packet for transmission as the port finishes
+transmitting the previous last packet in the queue (per channel and queue).
+  - RxMisQCnt: Incremented when host queues adds buffers to a queue as the port finished the
+reception of the previous last packet in the queue (per channel).
+  - TxEOQCnt: Number of times the port has reached the end of the transmit queue (per channel and queue).
+  - RxEOQCnt: Number of times the port has reached the end of the receive queue (per channel).
+  - RxPacketsServiced: Number of received packets (per channel).
+  - TxPacketsServiced: Number of transmitted packets (per channel and queue).
+  - RxMaxServiced: Maximum number of packets that the CPHAL receive interrupt has serviced at a time (per channel).
+  - TxMaxServiced: Maximum number of packets that the CPHAL transmit interrupt has serviced at a time (per channel and queue).
+  - RxTotal: Total number of received packets, all channels.
+  - TxTotal: Total number of transmitted packets, all channels and queues.
+- Level 2 Statistics (CPHAL Flags)
+  - RcbPool: Pointer to receive descriptor pool (per channel).
+  - RxActQueueCount: Number of buffers currently available for receive (per channel).
+  - RxActQueueHead: Pointer to first buffer in receive queue (per channel).
+  - RxActQueueTail: Pointer to last buffer in receive queue (per channel).
+  - RxActive: 0 if inactive (no buffers available), or 1 if active (buffers available).
+  - RcbStart: Pointer to block of receive descriptors.
+  - RxTeardownPending: 1 if Rx teardown is pending but incomplete, 0 otherwise.
+  - TcbPool: Pointer to transmit descriptor pool (per channel and queue).
+  - TxActQueueCount: Number of buffers currently queued to be transmitted (per channel and queue).
+  - TxActQueueHead: Pointer to first buffer in transmit queue (per channel and queue).
+  - TxActQueueTail: Pointer to last buffer in transmit queue (per channel and queue).
+  - TxActive: 0 if inactive (no buffers to send), or 1 if active (buffers queued to send).
+  - TcbStart: Pointer to block of transmit descriptors.
+  - TxTeardownPending: 1 if Tx teardown is pending but incomplete, 0 otherwise.
+- Level 3 Statistics (CPHAL Channel Configuration)
+  - RxBufSize: Rx buffer size.
+  - RxBufferOffset: Rx buffer offset.
+  - RxNumBuffers: Number of Rx buffers.
+  - RxServiceMax: Maximum number of receive packets to service at a time.
+  - TxNumBuffers: Number of Tx buffer descriptors.
+  - TxNumQueues: Number of Tx queues to use.
+  - TxServiceMax: Maximum number of transmit packets to service at a time.
+- Level 4 Statistics (CPHAL General Configuration)
+  - Base Address: Base address of the module.
+  - Offset (VLYNQ): VLYNQ relative module offset.
+  - Interrupt Line: Interrupt number.
+  - Debug: Debug flag, 1 to enable debug.
+  - Inst: Instance number.

+
+The CPMAC implementation will support 8 channels for transmit and 8 channel for
+receive.  Each of the 8 transmit channels has 1 queue associated with it.  It is
+recommended that only 1 channel is used for @c Receive() per processor.

+@par osReceive
+@p Mode parameter
+- The Upper 16 bits of Mode match Word 3 of the Rx Buffer Descriptor
+
+@par halSend
+@p Mode parameter
+-  Bits 0-7 contain the Channel Number
+-  Bits 8-25 are reserved
+-  Bit  26 - if 0, the CRC will be calculated, if 1 the CRC will be Passed
+-  Bits 27-31 : reserved
+@section cpmac_keys Control Keys
+
+@par StateChange
+CPHAL calls the OS when a state change is detected.
+OS should check the CPMAC Status. See the Control Key 'Status' for more details.
+
+@par Status
+OS calls the CPHAL to obtain Status information. The Returned status is as follows
+
+@par MaxFrags
+The OS may "Set" or "Get" this value.  This defines the maximum
+number of fragments that can be received by the CPMAC Rx port.  The default
+value for CPMAC is 2.  This provides enough space to receive a maximum
+length packet (1,518 bytes) with the default buffer size of 1518 and any
+amount of RxBufferOffset.  If the buffer size is configured to be smaller,
+the OS *MUST* modify this parameter according to the following formula:
+((System Max packet length)/(RxBufSize)) + 1.  (The extra 1 fragment is to
+allow for RxBufferOffset)
+
+@code
+// Following defined in "cpswhal_cpmac.h"

+@endcode
+
+@par Tick
+     The CPHAL calls the OS to set the interval for calling halTick()<BR>
+     Note: Predefined value hcTick now recommended for use.
+@code
+***  Example Code ***
+
+*** CPHAL code ***
+int Ticks;
+HalDev->OsFunc->Control(HalDev->OsDev, hcTick, hcSet, &Ticks);
+
+*** OS code ***
+  ..

+      // Enable the Tick Interval
+      if(*(unsigned int *) ParmValue)
+        printf("osTickSet: Interval = %d ticks\n", Interval);
+    }
+    else
+    if(osStrcmpi(pszAction, hcClear) == 0)
+    {
+        // Request disabling of the Tick Timer, ParmValue is ignored
+    }
+  }
+@endcode
+
+@par The following information can be obtained by the OS via 'Get'
+
+- StatsDump : OS supplies pointer to an 36 element unsigned int array
+CPHAL will populate the array with the current Statistics values.<BR>
+Note: all hcXXXX values are predefined and should be used by the OS.
+
+- hcPhyNum : Returns the PHY number.
+- hcCpmacBase : Returns the base-address of the CPMAC device
+- hcCpmacSize : Returns size of the CPMAC memory map
+
+
+@par Phy Register Communication
+
+halControl() is used to read and write the Phy Registers via the key hcPhyAccess
+
+Both reading and writing the Phy registers involve setting the Value parameter of halControl()
+<BR>
+Value is a 32-bit value with bits partioned as follows
+<BR>
+
+   0 -  4  Phy Number   <BR>
+   5 -  9  Phy Register <BR>
+  10 - 15  reserved     <BR>

+@page auto_mdix Auto Mdix Support
+
+Auto Mdix selection is controlled by two elements in the CPMAC. First the OS can turn Auto Midx On or Off by the use of the
+MdioConnect field, _CPMDIO_AUTOMDIX. This is defaulted ON.  For actual Auto Mdix operation the Phy must also be Auto Mdix capable.
+This is specified by the DeviceFindxxx() field, "MdixMask" (supplied as the variable hcMdixMask).
+If both these fields are set then the CPMDIO state machine will be enabled for Auto Mdix checking.
+If a switch to MDI or MDIX mode is needed, the CPMAC will signal this to the OS via Control() using

+ * <key, info> pair. It is possible to have multiple occurrence of the same key. 
+ * Multiple occurences of the same keys are referred to as 'instances'. 
+ * 'instances' are assigned in the order of configuration arrival. The first 
+ * config for a 'key' added to the repository would be treated as instance 0 and
+ * next config to arrive for the same key would be treated as instance '1' and 
+ * so on.
+ * 
+ * Info is retrieved from the repository based on the 'key' and 'instance' value.
+ *
+ * No assumption is made about the format of the information that is put in the 
+ * repository. The only requirement is that 'key' should be NULL terminated 
+ * string.

+ * DESCRIPTION:     Storing and retrieving the configuration based on key
+ * A set of APIs to be used by one and sundry (including drivers and enumerator) to build

+ *
+ * This set of APIs isolates the configuration management from the world and provides simple

+ *
+ * Device in this set refers to the peripherals that can be found on the SOC or on VLYNQ.
+ * The configuration is stored in the form of string and drivers can use these APIs to get
+ * a particular parameter value.
+ *
+ * The memory allocation for the pass back parameters is done by the caller.
+ *
+ * 0 is returned for SUCCESS or TRUE.
+ *  -1 is returned for FAILURE or FALSE.

+           REL_20030701_HALdallas_cpsar_01.06.02
+
+Bug fixes: 1) A previous firmware upgrade caused firmware OAM loopback cells to only work on every other
+              command.  This has been fixed in the new firmware version (0.47).
+           2) Problem with PTI values changing on transparent mode packets has been resolved.
+           3) Previously, successful firmware OAM loopback cells waited 5 seconds before notifying the
+              OS of success, rather that notifying immediately.  This has been resolved in firmware.
+           4) PITS #148 (MAC and SAR), #149 (MAC) have been fixed.
+
+New features: 1) AAL5 HAL now capable of receiving unknown VCI/VPI cells on a single transparent channel.
+                 See updated HAL document (AAL5 appendix) for implementation details.
+              2) AAL5 HAL now allows OS to modify the OAM loopback timeout window.  Previously, failed
+                 OAM loopback attempts timed out after a nominal 5 seconds (based on the SAR frequency
+                 provided by the OS).  Now, the default is 5 seconds, but the OS may change the
+                 value via halControl() to any integer number of milliseconds.  See updated HAL document
+                 (AAL5 appendix) for implementation details.
+              3) MAC (cpmdio): added loopback to Istate.  Used for debug.
+
+Known issues not addressed in this release: NTR.
+
+09 June 2003         CPSAR 1.6.1 (external release), CPMAC 1.6.1 (internal release - no functional change)
+
+Note: This is the same set of fixes being applied to 1.6.0 that were applied to 1.5.3.  The only difference
+      between 1.6.1 and 1.5.4 is that 1.6.1 has the TurboDSL fix.

+           REL_20030530_HALdallas_cpsar_01.05.03
+
+Bug fixes: NTR.
+
+New features: 1) AAL5 Send() has been modified to accept an ATM Header either in the first
+                 fragment by itself, or in the first fragment directly in front of payload data.
+                 The API() does not change.
+              2) Documentation updates throughout, reflected in latest version of CPHAL user's
+                 guide.
+              3) AAL5 MaxFrags default value is now 46.  This is based upon the default AAL5
+                 RxBufSize of 1518 (MaxFrags = (65568/1518) + 2).  IF THE OS CHOOSES A SMALLER
+                 RxBufSize, IT MUST INCREASE THE VALUE OF MaxFrags ACCORDINGLY.  This is done
+                 via halControl(), prior to Open().
+
+Known issues not addressed in this release:
+              1) The Linux SAR driver is seeing an issue in which it cannot
+                 reliably send traffic simultaneously on both the high and
+                 low priority queues of a single AAL5 channel. (TurboDSL)
+
+23 May 2003         CPHAL 1.5.2 (external release)

+           REL_20030523_HALdallas_cpsar_01.05.02
+
+Bug fixes: 1) PITS #138: CPMAC flooding issue resolved.
+           2) PITS #142: OS may now set "MaxFrags" via Control().  This controls the
+              maximum number of fragments expected by the CPHAL.  The default value is 2 for
+              CPMAC and 1028 for AAL5.  If the OS chooses a RxBufSize that will cause more
+              fragments than the defaults, the OS must set "MaxFrags" to a correct value
+              ((maximum packet length / RxBufSize) + 2).
+           3) PITS #143: Fixed.
+           4) Firmware OAM bug fixed. (new firmware release in this version)
+
+New features: NTR.
+
+Known issues not addressed in this release:

+           REL_20030514_HALdallas_cpsar_01.05.01
+
+Bug fixes:    1) PITS 132 - (CPMAC) Frames < 60 bytes and split into
+                             multi-fragments.
+              2) BCIL MR PSP00000353 - (CPMAC) PhyDev not free'd on halClose()
+              3) PITS 113 - OsSetup bug in ChannelSetup fixed.
+              4) Fixed AAL5 to check return values of InitTcb/InitRcb.
+              5) Fixed Shutdown to properly free resources in the case of a Close
+                 mode 1 followed by Shutdown.  Previously, buffer and descriptor
+                 resources were left unfreed in this case.
+
+New features: 1) AAL5 Send() modified to be capable of accepting ATM header as first four
+                 bytes of first fragment.  This allows the OS to "override" the
+                 default ATM header which is constructed from preconfigured channel
+                 parameters.
+              2) AAL5 Receive() modified to be capable of passing the received ATM header (4 bytes, no HEC)
+                 in the first fragment (by itself).  It also passes up the OS an indication
+                 of what the received packet type was.  For Host OAM and transparent mode
+                 packets, the ATM header is passed in this manner, and for other types of packets
+                 (AAL5, NULL AAL) no ATM header is passed currently.
+
+Known issues not addressed in this release:

+           REL_20030430_HALdallas_cpsar_01.05.00
+
+Bug fixes:   1) Fixed AAL5 bug that rendered the low priority queue
+                unusable.
+             2) Fixed a bug in AAL5's Oam Rate calculations.
+             3) Fixed use of "DeviceCPID" key in AAL5's halControl().
+             4) Fixed RxReturn logic in HAL.  The HAL now can handle
+                failing MallocRxBuffer calls when multiple fragments
+                are being used.
+
+New features: 1) AAL5 Stats now available on a per queue basis.
+              2) AAL5 adds two new keys to halControl() for "Set" actions:
+                 RxVc_OamCh and RxVp_OamCh.
+              3) Shutdown() has been modified for both AAL5 and CPMAC to
+                 call Close() if the module is still in the Open state.
+              4) CPMAC adds the following access keys to halControl():
+                 hcPhyAccess,hcPhyNum,hcCpmacBase,hcSize,and hcCpmacSize.
+              5) CPHAL no longer requests an extra 15 bytes on data buffer
+                 mallocs.
+
+Known issues not addressed in this release:
+              1) The Linux SAR driver is seeing an issue in which it cannot
+                 reliably send traffic simultaneously on both the high and
+                 low priority queues of a single AAL5 channel.

+
+Bug fixes:   1) Fixed OAM logic in SAR portion of CPHAL.
+
+New features: 1) OAM loopback counters exposed through halControl.
+              2) Host OAM Send() can now use a single channel to send
+                 OAM cells on unlimited number of VP's/VC's.
+              3) CPHAL now requests "SarFreq" through osControl.
+              4) CPHAL now calculates all OAM function rates based on
+                 "SarFreq"; function OamRateConfig removed for API.
+              5) New OAM function OamLoopbackConfig, used for configuring
+                 loopback functions in firmware OAM mode.
+
+Known issues not addressed in this release:  Bug fix 1) in release 1.4
+             (see below) does not work properly for multiple fragments.

+           REL_20030410_HALdallas_cpsar_01.04.00
+
+This release is for SAR and MAC.
+
+  Bug fixes: 1) Implemented logic in HAL to re-request buffer mallocs
+                in the case of MallocRxBuffer failing.  The HAL now maintains
+                a NeedsBuffer queue of all RCB's that are without buffers.
+                On interrupts, or on Send(), the HAL checks to see if any
+                RCB's are on the queue, and if so, calls MallocRxBuffer
+                to attempt to get a new buffer and return the RCB to
+                circulation.
+             2) SAR now properly returns all error codes from halOpen and
+                halChannelSetup.
+
+  New features: NTR
+
+  Known issues not addressed in this release: NTR
+
+08 April 2003         CPHAL 1.3.1 (internal release - SAR only)
+
+  CC Labels: REL_20030408_HALdallas_cpsar_01.03.01
+
+  This is a SAR only release.  The current CPMAC release is still 1.3.
+
+  Bug fixes: 1) PDSP State RAM / Scratchpad RAM is now completely cleared after reset.
+                This resolves a stability issue.
+
+  New features: 1) OamMode is now a parameter in halControl().  Both "Set" and "Get"
+                   actions are available.  The value may be "0" (Host OAM), or "1"
+                   (Firmware OAM).
+
+  Known issues not addressed in this release:
+             1) Appropriate action for HAL in the case of MallocRxBuffer failing.  We
+                are investigating whether the HAL should implement a needs buffer
+                queue.

+
+  This release requires no changes for the ethernet end driver.  The changes necessary
+  for the sar driver (firmware file name changes) have already been implemented.
+
+  Bug fixes: 1) RxReturn now returns an error if MallocRxBuffer fails.  On RxReturn error, the driver should
+                call RxReturn again at a later time (when the malloc may succeed) in order for the CPHAL
+                to maintain a full complement of Rx buffers.  We recommend holding off making this driver
+                change until we verify that this condition occurs.
+
+  New features: 1) Removed benign compiler warnings.
+                2) PITS 122: http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=122
+                3) Cpsar label (above) now is applied to everything
+                   beneath /cpsar.
+                4) PITS 14: http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=14
+                   Transferred to MR PSP 00000089.

+                Future release will make OamMode configurable
+                through halControl(), not on per channel basis.
