[dpdk-stable] patch 'net/mlx5: fix max number of queues for NEON Tx' has been queued to LTS release 17.11.7

[Yongseok Koh]

Hi,

FYI, your patch has been queued to LTS release 17.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objection by 07/27/19. So please
shout if anyone has objection.

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.

Thanks.

Yongseok

Subject: [PATCH] net/mlx5: fix max number of queues for NEON Tx

[ upstream commit 9cc42c58931a428a94e9adf7019eb97faa8fddb1 ]

BlueField SmartNIC has 0xa2d2 as PCI device ID on both ARM and x86 host. On
ARM side, Tx inlining need not be used as PCI bandwidth is not bottleneck.
Vectorized Tx can still be used up to 16 queues. For other archs
(e.g., x86), keep using the default value.

Fixes: 09d8b41699bb ("net/mlx5: make vectorized Tx threshold configurable")
