Hi,

FYI, your patch has been queued to stable release 20.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/20/22. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/c4a4ba788f6369745ca3a5aa70a7c3f1f8d69be0

Thanks.

Subject: [PATCH] net/bonding: fix reference count on mbufs

[ upstream commit 814e79f3afad8c45c6922617f26292af3221ae2b ]

In bonding Tx broadcast mode, Packets should be sent by every slave,
but only one mbuf exits. The solution is to increment reference count
on mbufs, but it ignores multi segments.

This patch fixed it by adding reference for every segment in multi
segments Tx scenario.

Fixes: 2efb58cbab6e ("bond: new link bonding library")
