From 58a95badbd138950300f1fc2614cc83c255fc444 Mon Sep 17 00:00:00 2001 From: Tal Shnaiderman Date: Tue, 12 Oct 2021 15:45:52 +0300 Subject: [PATCH] common/mlx5: read FCS scattering capability from DevX 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.
