[PATCH mlx5-next 2/4] net/mlx5: Add function_id_type for enable/disable_hca cmds

From: Tariq Toukan

Date: Tue Apr 28 2026 - 01:41:22 EST


From: Moshe Shemesh <moshe@xxxxxxxxxx>

Add a function_id_type field to the enable_hca and disable_hca command
input layouts in mlx5_ifc.h to allow using vhca_id as the function index
instead of function_id. The new field support by firmware is indicated
by the function_id_type_vhca_id capability bit, which is already exposed
in hca caps.
