Hi,
FYI, your patch has been queued to stable release 24.11.3
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/23/25. 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/kevintraynor/dpdk-stable
This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/881863c82012133d22eedcad15b8cf46c17dc41e

Subject: [PATCH] net/txgbe: fix reserved extra FDIR headroom
[ upstream commit 3f5886d6435eb7e9add005d8e7dc880841a51465 ]
Remove redundant 256KB FDIR headroom reservation. FDIR headroom was
already allocated in txgbe_fdir_configure() when FDIR is enabled, the
second reservation resulted in 256KB less available RX packet buffer than
the theoretical size.
Fixes: 8bdc7882f376 ("net/txgbe: support DCB")
