[dpdk-stable] patch 'net/bnxt: fix mbuf free when clearing Tx queue' has been queued to LTS release 18.11.6

[Kevin Traynor <ktraynor@redhat.com>]

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/34afffbb2f7f29d9c1e1ac994b10fa6328fdd075

Thanks.

Kevin.

Subject: [PATCH] net/bnxt: fix mbuf free when clearing Tx queue

[ upstream commit 00932678c6bbbe922a2790e59fd68b34719f3171 ]

When freeing pending transmit mbufs, use rte_pktmbuf_free_seg()
instead of rte_pktmbuf_free(), otherwise linked mbufs may be freed
more than once.

Fixes: 6eb3cc2294fd ("net/bnxt: add initial Tx code")
