----------------------------------------
  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:

Version 11.16  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.        
        
        
Version 11.15  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.

  Enhancements:
  =============
  1.  Request:
        CQ34973 - OEM requests to enable log options for sysetms w/ 5784M

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

      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 11.10  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:
        Add driver support back for Windows 2000.
      Change:
        Modify inf files for installing driver on Windows 2000.

  3.  Request:
        CQ33892 - Add 4 part IDs for specific OEM
      Change:
        Added new IDs.
 
  4.  Request:
        CQ25155 - 5784M/5764M/5723/5761/5761E implementation of this CQ is
        done in hardware instead of the software implementation.
      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 11.9  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:

  1.  Problem:
        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 11.7 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.


Version 11.6  January 24, 2008
----------------------------------------
  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
        during external loopback test.
      Impact:
        Resolve CQ33519.

  3.  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.

  4.  Request:
        Implement new GPHY Workaround for 5784M/5764M/5723 B0.

----------------------------------------
  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.

      Change:
        Configure LED Mode default to MAC Mode for 5784M A0 & A1.


Version 11.2  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:
