[dpdk-stable] patch 'net/ena: fix parsing of large LLQ header device argument' 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 06/14/21. 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/a5c0cca39ad6d6c78476734f4ae4f92640783e9d

Thanks.

Subject: [PATCH] net/ena: fix parsing of large LLQ header device argument
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 9b312ad310024d00822cbc431677b59daa1e5e2c ]

The code incorrectly checked the return value of comparison when parsing
the argument key name. The return value of strcmp should be compared
to 0 to identify a match.

Fixes: 8a7a73f26cc9 ("net/ena: support large LLQ headers")
