> This brings the DPDK igb driver inline with the behavior used by the current Linux
> driver. The IGB hardware has several different MAC types and the threshold
> values that work vary based on the hardware.
> 
> Since DPDK 1.8 it has been up to devices to provide the correct default
> configuration parameter. But the igb driver gives values that are broken on
> some devices, and always causes a warning message at startup.
> 
> Please test this on real hardware, I don't have the luxury of a hardware lab full
> of variations of this chip.
