Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/56aaa9bff17f21ac51eac7402a9426be5982eaac

Thanks.

Luca Boccassi

Subject: [PATCH] net/octeontx2: fix PF flow action for Tx

[ upstream commit 701f94a60afbc7c3e28766cc88afa1b5397fdfba ]

pf-func is 16bit but the current reserved location
used in tx action is 8bits. Moved it to bits 63-48.

Fixes: 32e6aaa97c40 ("net/octeontx2: support flow parse actions")
