[PATCH mlx5-next 2/8] net/mlx5: Add silent mode set/query and VHCA RX IFC bits
From: Tariq Toukan
Date: Sun Mar 08 2026 - 01:58:34 EST
From: Shay Drory <shayd@xxxxxxxxxx>
Update the mlx5 IFC headers with newly defined capability and
command-layout bits:
- Add silent_mode_query and rename silent_mode to silent_mode_set cap
fields.
- Add forward_vhca_rx and MLX5_IFC_FLOW_DESTINATION_TYPE_VHCA_RX.
- Expose silent mode fields in the L2 table query command structures.
Update the SD support check to use the new capability name
(silent_mode_set) to match the updated IFC definition.
