patch 'net/txgbe: fix FDIR mode clearing' has been queued to stable release 23.11.6

[Shani Peretz]

Hi,

FYI, your patch has been queued to stable release 23.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/30/25. 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/shanipr/dpdk-stable

This queued commit can be viewed at:
https://github.com/shanipr/dpdk-stable/commit/b37e7cf39d4ce667bed46babfc8a7512b12154a5

Thanks.

Shani

Subject: [PATCH] net/txgbe: fix FDIR mode clearing

[ upstream commit 26048c25942f2579a821a99b78db48fdb2c90c77 ]

When FDIR flow rules are all cleared, FDIR mode is not cleared. This will
cause that creating new FDIR flow rules failed, for their mode are
different from the previously deleted ones.

Fixes: 6bde42fe7fa5 ("net/txgbe: flush all filters")
