[dpdk-stable] patch 'net/sfc: fix VF error/missed stats mapping' has been queued to LTS release 17.11.6

[Yongseok Koh]

Hi,

FYI, your patch has been queued to LTS release 17.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objection by 03/13/19. So please
shout if anyone has objection.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

Subject: [PATCH] net/sfc: fix VF error/missed stats mapping

[ upstream commit 24f8a95917b36b313a49bd604c3958f992893efd ]

VADAPTER_RX_OVERFLOW means Rx statistics overflow, not a missed
packet because of overflow.

VADAPTER_RX_BAD_PACKETS accumulates a number of error conditions,
but mainly impossibility to deliver because of no descriptors
available, so it is better to classify it as imissed.

Fixes: 1caab2f1e684 ("net/sfc: add basic statistics")
