[PATCH v2] net/mlx5: fix Windows flow table and queue routine

Sun Nov 6 04:26:16 CET 2022


The macro HAVE_MLX5_HWS_SUPPORT was introduced for HWS only. And
HWS was not supported on Windows. So macro HAVE_MLX5_HWS_SUPPORT
should be only around the code which HWS uses, but avoid including
the code block shared by Linux and Windows.

Fixes: 22681deead3e ("net/mlx5/hws: enable hardware steering")
