patch 'pdump: clear statistics when enabled' has been queued to stable release 24.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/28/25. 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/aa006690018044577d7e532bb8e549c3868d2944

Thanks.

Kevin

Subject: [PATCH] pdump: clear statistics when enabled

[ upstream commit b8392fa204ed46b580d61e7621948f1b187c9f98 ]

The pdump statistics are used to keep track of the number
of packets captured, filtered, etc. These need not be cumalative
and instead should be start counting when capture starts.

This fixes the issue where multiple invocations of dumpcap
would include counts from previous invocations.

Bugzilla ID: 1604
Fixes: 10f726efe26c ("pdump: support pcapng and filtering")
