Hi Jingjing,

What is a "programming packet"?

I'd really like to stop seeing this kind of thing.
We cannot add some ifdef for each PMD in generic code.

I stopped reading after that.

Sorry, I don't want to be rude but my feeling is that adding such feature
with global picture in mind is not easy. I know you want to offer all i40e
capabilities but you should think at future evolutions and how other drivers
will be integrated with yours.

Thanks
