    ixgbe: Remove the Adaptative Interrupt Moderation code
    
    * It didn't work correctly, the number of ixgbe interrupts per second
      could become excessive
    
    * Use a fixed rate for all interrupts, be they legacy, MSI or
      MSI-X vectors. 8000 intr/s is a good default value.
    
    * This change increases single stream tcp performance up to almost 50%
      in the sending direction
