Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/943b236c09cc7d1fbb370ba897b05f5fff6bf418

Thanks.

Luca Boccassi

Subject: [PATCH] examples/l2fwd-event: fix port statistics memset

[ upstream commit 02a4f7a278164cc4de9ce8d4abd681efd7c1c071 ]

port_stats is declared as struct l2fwd_port_statistics[RTE_MAX_ETHPORTS],
but the memset passed sizeof(struct l2fwd_port_statistics) -- the size
of a single element -- leaving ports 1 through RTE_MAX_ETHPORTS-1 with
uninitialized stats. Use sizeof(rsrc->port_stats) to clear the whole
array regardless of RTE_MAX_ETHPORTS.

Surfaced as a -Wmemset-elt-size warning when building with
-Dmax_ethports=64 -Dexamples=all.

Fixes: 4ff457986f76 ("examples/l2fwd-event: add default poll mode routines")
