4. RESOLVED ISSUES

  4.1 ISE

    v5.5 Rev 1
    
    - Programming the AVB specific frame filters also changes the non-AVB filter at 
      the same offset
    - CR704839
    
    - The TX stats byte count is incorrect if the TX IFG drops below 8.
    - CR687357 
    
    - When using the TX IFG input, the smallest value which can be obtained
      in full duplex mose (with half duplex supported) is 9 bytes
    - CR695056
    
    v5.5
    
    - A Pause request during transmission of a PAUSE frame can corrupt the Quanta
    - CR 687357
    
    - Frames within 12 bytes of the user defined max frame size could get marked bad
    - AR 52556
    
    - RGMII_TX_ER incorrect timing at 10/100 speeds 
    - CR 680540
