Hi,

FYI, your patch has been queued to stable release 22.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/25. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/cf8d97141b2f57ac6419a0c5cd97e27b1d4e4333

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: allow Tx vector when fast free not enabled

[ upstream commit e05cb702ca70aecdf01041274cd6ffc9233a726d ]

Currently, the Tx vector algorithm is only enabled
when tx_offload is RTE_ETH_TX_OFFLOAD_MBUF_FAST_FREE.
If no offloads are enabled, then vector algorithm can also be used.
The vector algorithm does not support other transmit offloads.

Fixes: e31f123db06b ("net/hns3: support NEON Tx")
