[luca.boccassi at gmail.com]

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/0a369930ac1d056ca4dac73a265d71b08f341958

Thanks.

Luca Boccassi

Subject: [PATCH] net/intel: fix use of offload validation function

[ upstream commit 8099ff1275dab3e093c836c59ac99182be4d396c ]

rte_validate_tx_offload() returns 0 on success.  The i40e, iavf and ice
drivers treat any non-zero return as an error and drop the packet,
causing valid packets to be dropped when Tx offload checking is enabled
via EAL, e.g.:

    -a 81:00.0,mbuf_check=offload

Only reject the packet when the return value is not 0.

Fixes: 82b03af55a1b ("net/i40e: support mbuf checks in Tx path")
Fixes: 21dad1fc78cb ("net/iavf: support mbuf checks in Tx path")
Fixes: 2a0244d611b4 ("net/ice: support mbuf checks in Tx path")
