[dpdk-dev] [PATCH v1] i40e: Fix the statistics issue of i40e

[Xutao Sun]

The old statistics on i40e only count the packets on ports.
This patch is to make statistics for packets both on ports and VSI.
But there're still some issues about statistics for 'bytes'.

It is not needed to have a separate commit for the documentation in this case.

Indeed there is an issue in i40e stats, and adding the VSI stats to the port stats seems the right fix.

It is preferred to update docs in the same patch as a bugfix: one patch should suffice for a bug-fix and adding a note that it has been fixed.

Perhaps you edited the wrong release file? The next release changes are described in release_2_2.rst

Would you send a v4 with release_2_2 updated, and then I'll test and ack?
Cheers, -Harry

My patch is different from Harry's patches for extended stats actually.
My modification for stats has no intersection with Harry's.
So maybe I don't  need to rebase on Harry's patches.

When I can manage the merge myself safely, I don't ask.
Please rebase on current master.
