[dpdk-stable] patch 'net/mvpp2: fix non-EAL thread support' has been queued to stable release 19.11.4

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 19.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/26/20. 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.

Thanks.

Luca Boccassi

Subject: [PATCH] net/mvpp2: fix non-EAL thread support

[ upstream commit b52d25ae4b1bbe9adba0d9276b7771ec27e3d151 ]

Caught by code inspection, for a non-EAL thread identified with
rte_lcore_id() == LCORE_ID_ANY, the code currently arbitrarily uses
lcore 0 while there is no guarantee this lcore is used.

Fixes: 3588aaa68eab ("net/mrvl: fix HIF objects allocation")
