Hi,

FYI, your patch has been queued to stable release 20.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/21/23. 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/5d3142ed48fd78d8a4781cb8da47e519038af3ce

Thanks.

Luca Boccassi

Subject: [PATCH] net/iavf: remove log from Tx prepare function

[ upstream commit 4015aed58aefb3cceba6766f1fcaaa483c21ede0 ]

iavf_prep_pkts reports to the application that the packet is invalid
(from the driver pov). Having a log message only in this branch is not
consistent with all other checks in this function and it may slow down
the application if such invalid packets are being sent continuously.

Fixes: 19ee91c6bd9a ("net/iavf: check illegal packet sizes")
