[dpdk-stable] patch 'net/i40e/base: gracefully clean the resources' has been queued to LTS release 16.11.9

[Luca Boccassi]

Hi,

FYI, your patch has been queued to LTS release 16.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/17/18. 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. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Luca Boccassi

Subject: [PATCH] net/i40e/base: gracefully clean the resources

[ upstream commit 49ea51605be46b48b12c2267b7c2a12d5ed1ed07 ]

Allocated resources were not freed in the event of failure in
i40e_init_asq function. This patch gracefully handles all failures.
