[dpdk-stable] patch 'net/i40e: fix address of first segment' has been queued to LTS release 18.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/16/19. 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/2ecdb1da978fb5d3b508f7b2c78fc44c95d6d9e6

Thanks.

Kevin.

Subject: [PATCH] net/i40e: fix address of first segment

[ upstream commit ff4f8e24d535df81557f3dcef64d1aef8251f277 ]

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: 343422, 343403
Fixes: ca74903b75cf ("net/i40e: extract non-x86 specific code from vector driver")
