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/8189e99b3a5f743b1b7ecd3cb1553d6e49a26a78

Thanks.

Luca Boccassi

Subject: [PATCH] net/ixgbe: check filter init failure

[ upstream commit 8c1e5c658c24553d5f813adc8afed8910e6f5194 ]

The function ixgbe_fdir_filter_init() and ixgbe_l2_tn_filter_init()
could return errors, the return value need to be checked and returned.

Fixes: 080e3c0ee989 ("net/ixgbe: store flow director filter")
Fixes: d0c0c416ef1f ("net/ixgbe: store L2 tunnel filter")
