Hi, the first of these 2 squashed patches in isolation caused a
regression found by Intel validation team which required a lot of
investigation and it being reverted at the last moment before 18.11.2.
In this case I would like an Ack from Zhao and one of the testpmd
maintainers that they will support this before applying the patch below.
thanks,
Kevin.
