patch 'net/nfp: fix set IPv6 flow action' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/11/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/log/?h=22.11-staging/commit/dcc0be2c8a8ffa634c5b2128f27708f0887b5925

Thanks.

[ upstream commit 784835e690e011754a67a240fdc6154ea349ec20 ]

The former logic of set IPv6 source/destination address flow action
don't consider the mask filed of control message passed to the firmware.
This caused the firmware skip the set action logic, and the offloaded
packets don't have the right IPv6 address as expected.

Fixes: 596ae2217214 ("net/nfp: support IPv6 source flow action")
Fixes: 51384f79b264 ("net/nfp: support IPv6 destination flow action")
