patch 'pcapng: fix variable shadowing' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/02/26. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/10a44e8b8d38e95e127e70b090161718e4e92a1e

Thanks.

Kevin

Subject: [PATCH] pcapng: fix variable shadowing

[ upstream commit f6323a2561b673665550fe3696702ee815ae0f11 ]

The "len" variable is shadowed within a function, so rename inner use to
the more descriptive "filter_len" to fix the issue.

Fixes: d1da6d0d04c7 ("pcapng: require per-interface information")
