patch 'net/mlx5: fix number of supported flex parsers' has been queued to stable release 23.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/30/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=2ab85e98b8bf7c5e6f56d85a9e40f97106da4550

Thanks.

Subject: [PATCH] net/mlx5: fix number of supported flex parsers
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 16d8f37b4ebb59a2b2d48dbd9c0f3b8302d4ab1f ]

The hardware supports up to 8 flex parser configurations.
Some of them can be utilized internally by firmware, depending on
the configured profile ("FLEX_PARSER_PROFILE_ENABLE" in NV-setting).
The firmware does not report in capabilities how many flex parser
configuration is remaining available (this is device-wide resource
and can be allocated runtime by other agents - kernel, DPDK
applications, etc.), and once there is no more available parsers
on the parse object creation moment firmware just returns an error.

Fixes: db25cadc0887 ("net/mlx5: add flex item operations")
