Subject: [dpdk-dev] [PATCH v2 11/13] common/mlx5: read FCS scattering capability from DevX
Date: Tue, 12 Oct 2021 15:45:52 +0300	[thread overview]
Message-ID: <20211012124554.21296-12-talshn@nvidia.com> (raw)
In-Reply-To: <20211012124554.21296-1-talshn@nvidia.com>

mlx5 in Windows needs the hca capability scatter_fcs
to query the NIC support for the CRC keeping offload.

Added the capability as part of the capabilities
queried by the PMD using DevX.
