      Impact:
        None


Version 11.22.0.0  Sep 03, 2008
----------------------------------------
  1.  Problem:
        CQ37154 - OEM 5784M platform observes the same S5 WOL issue as CQ35234
      Cause:
        CQ35234 GPHY workaround was applied when system is going into S1/S3/S4, not for S5.
      Change:
        Apply CQ35234 GPHY workaround for S5 as well.
      Impact:
        None.

  2.  Problem:
        CQ35948: Bad TX performance BX630S2 W2K8
      Cause: The Tx code path runs out of credit on some of the processors, so aborts without
        sending anything. This is occuring because a software timer 
        failed to schedule the DPC responsible for calculating this credit. The DPCs were not 
        scheduled for more than 4 procs on x86 systems, and 8 procs on x64 systems. 
        This driver version fixes this problem
      Impact:
        None

  Enhancements:
  =============

Version 11.21.0.0  June 19, 2008
----------------------------------------
  1.  Problem:
        CQ35947 - B5764/B5761/B5784-When setting  WOL speed to 10mb system will be come unresponsive and lose link.
      Cause:
        The CQ35234 workaround is incorrectly executed when driver is loaded with WOL speed setting as 10mb.
        There is no problem when WOL speed is set to Lowest, Auto or 100mb.
      Change:
        Correct driver's abnormal behavior and make driver to apply the CQ35234 workaround precisely.
      Impact:
        None.

  2.  Problem:
        35434 - Win7 Inbox:  Please Remove OEM Pnp (product_string) from the driver INF.
      Cause:
      Change:
        Changed the inbox inf as requested.
      Impact:
        None.

  3.  Problem:
        35447 - Windows 7 Inbox:  Please Make INF Header consistent with NXII Driver INF.
      Cause:
      Change:
        Changed the inbox inf as requested.
      Impact:
        None.

  4.  Problem:
        35449 - Windows 7 Inbox: Incorrect "Provider" String under [Version) in Driver INF.
      Cause:
      Change:
        Changed the inbox inf as requested.
      Impact:
        None.

  5.  Problem:
        35450 - Windows 7 Inbox:  The Default Setting for Flow Control Should be Disabled per MSFT 
        Requirements.
      Cause:
      Change:
        Changed the inbox inf as requested.
      Impact:
        None.

  6.  Problem:
        35464 - Windows 7 inbox:  Power Management Feature (WOL) Not Disabled in the INF per MSFT Requirement 
        Requirements.

Version 11.20.0.0  June 9, 2008
----------------------------------------
  1.  Problem:
        CQ35239 - 5784m stops passing traffic when running copy compare at 10 Mb half duplex and ASPM L1 w/ clkreq.
      Cause:
        The clock glitch that occurring with L0->L1->L0 transitions causes device RDMA doesn't work normally.
      Change:
        Make driver to disable device's clkreq when linked at 10H or 100H as a workaround.
      Impact:
        Resolve CQ35239.

  2.  Problem:
        CQ35234 - 5784M/5764M will not assert Wake signal one the first Wake magic packet received.
      Cause:
        When device is connected to particular switch with specific PHY at 1G bps, with wol speed
        set to lowest speed, driver will program GPHY to advertise 10M bps support and restart 
        auto-negotiation while system is going from S0 to S3/S4/S5. In the meantime, 100tx or 1000t 
        idle sent from the link partner can confuse the local 10M bps polarity state machine, which 
        in turn can corrupt the first 10Mbps packet received.
      Change:
        Make driver workaround to reset link porlarity state machine and restart auto negotiation.
      Impact:
        Resolve CQ35234.        
        
  Enhancements:
  =============
  1.  Request:
        CQ31051 - FlowControl Parameter for Broadcom NX1 Not Consistent With Microsoft Standards
      Cause:
        There is a discrepancy between the MSFT and Broadcom naming convention as applied
        to the *FlowControl keyword.
      Change:
        Changed the BRCM naming convention to match the one MSFT mandates.      


Version 11.19.0.0  May 12, 2008
----------------------------------------
  1.  Problem:
        CQ34962 - 5784/5764/5761 system compatibility issue on particular OEM system.
      Cause:
        When BIOS sets root-complex's and device's Max Payload Size (MPS) to 256 bytes, 
        device's MPS will be incorrectly set to 128 by driver, then device will report 
        ERROR_FATAL and stop DMA when it makes Memory Read and receives completion
        packets larger than 128 bytes.        
      Change:
        Make driver to keep device MPS setting during initialization.
      Impact:
        Resolve CQ34962.

  2.  Problem:
        CQ34822 - Network traffic drops after SUT wakes up from S3/S4 while WOL is disabled.
      Cause:
        The reason why device doesn't pass traffic after system resuming from S3 (with 
        "Allow computer to turn off xxx" is unchecked) is because the upper layer doesn't use
        the OID_OFFLOAD_ENCAPSULATION OID to set the task offload encapsulation settings
        of an underlying miniport, and this makes our driver fails to send certain packets 
        which need driver/device to take care of checksum offload tasks. 
      Change:
        Make driver to cache/restore the OID_OFFLOAD_ENCAPSULATION parameters across suspend/resume.
      Impact:
        Resolve CQ34822.
        
  3.  Problem:
        CQ34959 - Modify NDIS 6.0 driver WoL behaviour when the "allow the computer to turn off 
        the device to save power" box is unchecked
      Cause:
        When driver's halt handler is called, driver enables device magic packet wol function according
        to nvram wol setting.
      Change:
        Make driver to take advantage of a HaltAction flag in the halt handler, then driver can use this 
        flag to determine the reason why it's Halt handler is called and behave accordingly.
      Impact:
        Resolve CQ34959.  
        
  Enhancements:
  =============
  1.  Request:
        CQ34973 - OEM requests to enable log options for sysetms w/ 5784M
      Change:
        Make inf changes to enable log options for OEM systems. 
      Impact:
        Resolve CQ34973.


Version 11.18.0.0  April 22, 2008
----------------------------------------
  1.  Problem:
        Ensure private OID buffer is not touched until signature
        is validated.
      Cause:
        Could cause DTM failure if buffer is modified
        when signature is invalid.
      Change:
        Move setting status until after signature is validated.
      Impact:
        None

  Enhancements:
  =============
  1.  Request:
        Enable constant 500Khz MDIO interface speed regardless core clock frequency.
      Change:
        Change driver to set the enable bit in MII Mode register.
      Impact:
        The change applies to devices 5764M/5784M/5723/5761/5761E.
        
        
Version 11.17.0.0  April 19, 2008

  1.  Request:
        CQ34699 - Add 4 part IDs for specific OEM
      Change:
        Added new IDs
  2.  Problem:
        CQ34762 - The system will casue blue screen when changed the 
        bootcode setting on b5761e-B0.
      Cause:
        BSOD if accessing Soledad's PCI FunctionEventMask register.
      Change:
        Not touch the register if it is Soledad
      Impact:
        None.

  3.  Problem:
        1c_ndisrequestcov may crash on newly added OIDs for new devices.
      Cause:
        Buffer size is incorrectly determined.
      Change:
        Change the driver to correctly detect the buffer size for affected
        OIDs.
      Impact:
        Fixed the BSOD on 1c_ndisrequestcov.
        
        
Version 11.16.0.0  March 31, 2008
----------------------------------------
  1.  Problem:
        CQ34467 - OEM system BSOD when running Copy/Compare test on Vista SP1 with 512MB RAM 
      Cause:
        When system is with 512MB memory only, driver allocates only 64K for LSO coalescing buffer. 
        There is a bug in handling coalescing pool wrapped around condition when 64K LSO coalescing 
        buffer is used. BSOD happens while driver is accessing memory over coalescing pool boundary.
      Change:
        Make code change to handle wrapped around condition correctly.
      Impact:
        Resolve CQ34467.


Version 11.15.0.0  March 16, 2008

----------------------------------------
  Enhancements:
  =============
  1.  Request:
        Enhance the fix for CQ33858.
      Change:
         Change CPMU Clock Policy Registers to increase the Core Clock Speed before issue 
         a GRC reset and restore these registers after boot code has completed initialization.
      Impact:
        Resolve CQ33858.


Version 11.12.0.0  February 24, 2008
----------------------------------------
  1.  Problem:
        CQ33858 - Device loses connection while doing load/unload test.
      Cause:
        When driver is unloaded, driver does a GRC Reset. When the link doesn't come back
        immediately, CPMU will put MAC core clock into slower speed. This makes boot code
        to be reloaed and executed slower. This also makes driver exceed waiting loop.
        Finally, GPHY register corrupted because of driver and boot-code racing condition.
      Change:
        Extend driver waiting time to make sure boot-code 2nd phase is finished.

  Enhancements:
  =============
  1.  Request:
        Remove CQ33808 driver workaround for 5784M/5764M/5723.
      Change:
        Remove driver workaround added in previous release.

        Bootcode v3.31 & slefboot patch v2.18 have the workaround to fix CQ33808.

  2.  Request:
        CQ33892 - Add 4 part IDs for specific OEM
      Change:
        Added new IDs

  3.  Request:
        CQ25155 - 5784M/5764M/5723/5761/5761E implementation of this CQ is
        done in hardware instead of the software implementation.
      Cause:
        New chip requiring different actions.
      Change:
        Activate hardware fix for this CQ in driver and not with code in
        the receive packet processing logic.
      Impact:
        New devices have hardware support for this fix that must be
        activated in the driver.


Version 11.11.0.0  February 11, 2008
----------------------------------------
  1.  Problem:
          CQ33808 - BCM5784M: System hangs when user changes Device Property with clkreq enabled.
      Cause:
          Issuing a GRC reset with clkreq enabled is causing a global chip reset and PCI-E
          completion timer timeout.
      Change:
          When ClkReq and L0s/L1 ASPM are enabled, driver will clear ClkReq enable bit before doing 
          GRC reset and restore it after GRC reset.
      Impact:
          Resolve C33808.

  Enhancements:
  =============
  1.  Request:
          Remove CQ33752 driver workaround.

        CQ33752 - Small fragments of less than 8 bytes cause transmit DMA failure.
      Cause:
        Under investigation.
      Change:
        Coalesce transmit buffers before submitting to the chip.
      Impact:
        Resolve issue for 5764M/5784M/5723/5761/5761E.


Version 11.9.0.0  January 29, 2008
----------------------------------------
  1.  Problem:
        CQ33564 - BACS MAC loopback test fails when test is running without cable.
      Cause:
        Bootcode version after v3.23 has enabled GPHY DLL Auto Power Down by default.
        When there is no cable, GPHY DLL Auto Power Down starts to work and makes test fail.
      Change:
        Change driver to disable GPHY DLL Auto-Power Down when running MAC loopback test
        and then retore GPHY DLL Auto-Power Down Bit to original value.
      Impact:
        Resolve issue and this is for 5764M/5784M/5723 B0 only.

  Enhancements:
  =============
  1.  Request:
        Add GPHY APD and GPHY DLL Auto-Power Down for 5764M/5784M/5723 B0.
      Change:
        Driver needs to read the share memory to determine how the GPHY Auto Power Down
        feature is enabled/disabled by the user.

  2.  Request:
        The GPHY workaround needs to be applied with the GPHY DLL Auto-Power Down Bit set.
      Change:
        Set GPHY DLL Auto-Power Down Bit before applying GPHY workaround and then restore
        GPHY DLL Auto-Power Down Bit to original value.
      Impact:
        This is for 5764M/5784M/5723 B0 only.

----------------------------------------
  1.  Problem:
        CQ33519 - 5784M fails at external loopback test fail.
      Cause:
        Device doesn't get linked and test application can't receive enough packets during the test.
      Change:
        Disable Link Speed/Link Aware/Airplane Power Mode and avoid setting PHY trim registers
        while in external loopback test.
      Impact:
        Resolve CQ33519

  Enhancements:
  =============
  1.  Request:
        Disable Link Speed/Link Aware/Airplane Power Mode while running MAC Loopback Test for 5784M B0.

  3.  Request:
        Enable IPV6 LSO support for 5764M/5784M/5723
      Change:
        Make driver to advertise IPV6 LSO capability for 5764M/5784M/5723.

  4.  Request:
        GPHY earl-wake-dac mode must be enabled before MAC 10mb rx only mode is enabled.
      Change:
        Whenever driver issues a reset to the GPHY, GPHY early-dac-dac mode will be disabled.
        Driver needs to disable CPMU 10mb rx only mode before resetting GPHY. Then later
        driver can re-enable the 10mb rx only mode. It's for 5764M/5784M/5723 B0 only.

  5.  Request:
        Implement new GPHY Workaround for 5784M/5764M/5723 B0.
      Change:
        Driver reads workaround parameters from OTP Memory and then configures GPHY accordingly.


Version 11.6.0.0  January 11, 2008
----------------------------------------
  1.  Problem:
          NDIS6 driver fails 1c_ioctlcoverage test.
      Cause:
          NDISTest is unable to query the OID : OID_GEN_SUPPORTED_GUIDS.

          Make driver to report successful status while doing the query.
      Impact:
          Passing 1c_ioctlcoverage test.


Version 11.5.0.0  January 11, 2008
----------------------------------------
  1.  Problem:
        CQ33072 - NDIS6 driver fails infTest in WLK 1.1
      Cause:
        Inf strings under [ParamsNT8021p] section are non-localizable.
      Change:
        Replaced hardcoded text with localizable strings.
      Impact:
        Resolve CQ33072.

  2.  Problem:
        CQ33122 - NDIS6 driver fails 2c_mini6rsssendrecv in Ndistest 6.0 of WLK 1.1
      Cause:
        There is a logical error in code and it makes driver can't disable RSS as ndistest
        expected while doing RSS disabling test with zero "Hash Function Information" and
        non-zero "Indirection Table Size".
      Change:
        Correct the logical error to make driver disable device RSS function successfully.
      Impact:
        Resolve CQ33122.

  3.  Problem:
        CQ32886 - Ndis6: SUT locks up when running cable analysis test while passing chariot traffic
      Cause:
        System hung while driver was trying to acquire a spin lock in UM_CheckForHang(). Driver was
        making two continuous main lock acquisitions. The first one came from UM_QueryInformation(),
        when BACS passed T3_OID_DIAG_SUSPEND to driver during the test. The second one came from
        UM_CheckForHang(), which was called by NDIS every two seconds.
      Change:
        Make driver doesn't acquire main lock in UM_CheckForHang while cable analysis is still running.
      Impact:
        Resolve CQ32886 issue.

  4.  Problem:
        CQ30853 - Soledad fails 1c_kernelcalls test script
      Cause:
        DbgBreakPoint() is used in free build driver
      Change:
        Remove DbgBreakPoint() from free build driver
      Impact:
        Resolve CQ30853 issue.

  5.  Problem:
        CQ30850 - Soledad fails 1c_wmicoverage test script
      Cause:
        The WMI method that ndistest is using does NOT return any class derived from Win32_PerfRawData class.
        It only returns "normal" WMI classes. However, the WMI class we provided is derived from Win32_PerfRawData
        class and it's used for graphing driver data to perfmon.exe along with some OS¡¦s provided perf data.
      Change:
        Create a registry key to control driver for enabling/disabling WMI perf counts.
      Impact:
        Resolve CQ30850 issue.

Version 11.4.0.0  December 10, 2007
----------------------------------------
  1.  Problem:
        CQ32573 - Failed to resume normal speedlink after power saving mode.
      Cause:
        Device has a problem with logic that handles the automatic switching of the burst mode
        to non-burst mode when the core clock is switching from 62.5MHz to slow clock modes.
      Change:
        Disable WDMA Rx Accel mode to workaround this issue.
      Impact:
        Resolve CQ32573 issue.

  2.  Problem:
        CQ32692 - BSOD in Vista with driver while running common scenario stress
      Cause:
        Driver incorrectly cleans 5784M RX return ring producer index during system suspend/resume
        from sleep. This makes driver get stuck when OS is trying put system into sleep again.
        While OS is telling driver to put device into D3, driver can't complete IRP (IRP_MJ_POWER
        /IRP_MN_SET_POWER) and this causes system BSOD with Bug check - DRIVER_POWER_STATE_FAILURE.
      Change:
        Make driver to behave correctly - not clean 5784M RX return ring producer index during
        system suspend/resume from sleep.
      Impact:
        Resolve CQ32692.

  Enhancements:

----------------------------------------

  Enhancements:
  =============
  1.  Request:
        Add support for 5784M A1 devices.
      Change:
        Make driver to keep all SW A0 workarounds for A1

  2.  Request:
        Disable Link Speed Mode and Link Aware Mode while running MAC Loopback Test for 5784M A0 & A1.
      Change:
        Make driver to disable Link Speed and Link Aware mode while running MAC loopback Test.

  3.  Request:
        For CQ31702 - SW needs to Configure LED Mode default to MAC Mode instead of GPHY Mode
      Change:
        Configure LED Mode default to MAC Mode for 5784M A0 & A1.


Version 11.2.0.0  October 24, 2007
----------------------------------------
  1.  Problem:
        CQ31830 - System hangs when put it into S3 and S4 or disable the adapter with WOL disabled.
      Cause:
        When WOL is not needed, driver will power down GPHY for saving power. When GPHY powers down,
        GPHY DLL stops provinding clock to mac core and this causes memory read completion timeout.
      Change:
        Make mac core clock switching before powering down GPHY.
      Impact:
        Resolve CQ31830 issue.

  Enhancements:
  =============
  1.  Request:
        CQ31815 - Blue screen on boot if no network cable attached.

      Change:
        Remove codes that enables GPHY APD (Auto Powerdown) in driver. The GPHY APD is now handled by
        the CPMU when Link Aware is enabled.

  2.  Request:
        CQ31619 - 5784M A0 failed DMA Write Engine Lock Up when Link Speed Mode Enabled with
                  10Mb Traffic and Core clock is 1.5MHz
      Change:
        Slow down the core clock to 6.25Mhz in 10mb, Link Aware Mode or 10mb Link Speed Mode for 5784M A0.
