Hi,
FYI, your patch has been queued to stable release 19.11.10
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/12/21. 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/cpaelzer/dpdk-stable-queue
This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/bc88f4ccfedf1d37d011f5ceb17f6cb7f3f983c2
Thanks.

Subject: [PATCH] net/octeontx2: use runtime LSO format indices
[ upstream commit 56cabfbf4affde4117652cba3c6235d1a40f4205 ]
Currently LSO formats setup initially are expected to be
compile time constants and start from 0.
Change the logic in slow and fast path so that LSO format indexes
are only determined runtime.
Fixes: 3b635472a998 ("net/octeontx2: support TSO offload")
