[dpdk-stable] patch 'net/avf: fix address of first segment' has been queued to LTS release 18.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 09/12/19. 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-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/a22b21347dfe3219b208ccc59d3e89f678cecdb0

Thanks.

Kevin Traynor

Subject: [PATCH] net/avf: fix address of first segment

[ upstream commit ba38f91468a896d9363e92261cbf17c6517e098a ]

This patch fixes (dereference after null check) coverity issue.
The address of first segmented packets was not set correctly during
reassembling packets which led to this issue.

Coverity issue: 343447
Fixes: 319c421f3890 ("net/avf: enable SSE Rx Tx")
