Good description! Thanks!

Acked-by: Jingjing Wu <jingjing.wu at intel.com> with minor comment:
The commit 5c9222058df7 ("i40e: move to drivers/net/") is just a moving i40e PMD driver code to current folder. It is not exactly that introduced the issue.
Maybe what you are looking for is 4861cde46116 ("i40e: new poll mode driver")


Thanks
Jingjing
