patch 'net/enetc: fix queue initialization' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/04/26. 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/c6b06d759f21569103d84cd3bbc1755c850df85b

Thanks.

Kevin

Subject: [PATCH] net/enetc: fix queue initialization

[ upstream commit b76f82be21ca55649cf3c9dc0aa3c2f6acfffda1 ]

Hardware can misbehave if the user tries to reset the consumer and
producer indexes without resetting the ring.

This patch adds the ring reset step before resetting the indexes.

Fixes: 6c9c5aadc0e0 ("net/enetc: support ENETC4 queue API")
