patch 'net/axgbe: reset end of packet in scattered Rx' has been queued to stable release 21.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/01/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/18895ee575c74388c6cd54dfa476f6209f252bc7

Thanks.

Kevin

Subject: [PATCH] net/axgbe: reset end of packet in scattered Rx

[ upstream commit 2a761aec228caf66025cacf07c7c9662ae021e03 ]

Reset the EOP in the failure scenario and also after the last segment.
Remove updating the packet length explicitly as it is done in chaining.

Fixes: 965b3127d425 ("net/axgbe: support scattered Rx")
