If anyone has any objections, please let me know. ------------------ From: Moshe Shemesh [ Upstream commit 8ca32460815f6876095be8798adcf5ab982e94de ] Several eswitch functions that only query other functions' HCA capabilities or read cached vport state are guarded by the vhca_resource_manager capability. This capability is required for set_hca_cap operations but query_hca_cap of other functions only requires the vport_group_manager capability. Relax the capability check from vhca_resource_manager to vport_group_manager in the following query-only paths: - mlx5_esw_vport_caps_get() - queries other function general caps - esw_ipsec_vf_query_generic() - queries other function ipsec cap - mlx5_devlink_port_fn_migratable_get() - reads cached vport state - mlx5_devlink_port_fn_roce_get() - reads cached vport state - mlx5_devlink_port_fn_max_io_eqs_get() - queries other function caps - mlx5_esw_vport_enable/disable() - vhca_id map/unmap Functions that perform also set_hca_cap (migratable_set, roce_set, max_io_eqs_set, esw_ipsec_vf_set_generic, esw_ipsec_vf_set_bytype) retain the vhca_resource_manager requirement.
