Subject: [PATCH 5/9] net/mlx5: fix number of supported flex parsers
Date: Wed, 11 Sep 2024 19:04:54 +0300	[thread overview]
Message-ID: <20240911160458.524732-5-viacheslavo@nvidia.com> (raw)
In-Reply-To: <20240911160458.524732-1-viacheslavo@nvidia.com>

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")
