[dpdk-stable] patch 'net/igc: fix Rx error counter for bad length' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/fa6df61bf20ad0017eb598eaccd6df10fa8498ac

Thanks.

Subject: [PATCH] net/igc: fix Rx error counter for bad length
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit c69abf624a3c84aa6b1cdfe953dcab9ff35deac2 ]

When the size of a packet in Rx channel is less than the minimum
or greater than the maximum, the packet will be simultaneously
counted by RLEC(Receive Length Error Count) and
RUC(Receive Under Size Count)/ROC(Receive Oversize Count) registers.

This patch fixes the issue of counting a length error packet twice
when counting the total number of received error packets.

Fixes: e6defdfddc3b ("net/igc: enable statistics")
