net/mlx5: E-Switch, Disallow vlan/spoofcheck setup if not being esw manager
In smartnic env, if the host (PF) driver is not an e-switch manager, we are not allowed to apply eswitch ports setups such as vlan (VST), spoof-checks, min/max rate or state. Make sure we are eswitch manager when coming to issue these callbacks and err otherwise. Also fix the definition of ESW_ALLOWED to rely on eswitch_manager capability and on the vport_group_manger. Operations on the VF nic vport context, such as setting a mac or reading the vport counters are allowed to the PF in this scheme. The modify nic vport guid code was modified to omit checking the nic_vport_node_guid_modify eswitch capability. The reason for doing so is that modifying node guid requires vport group manager capability, and there's no need to check further capabilities. 1. set_vf_vlan - disallowed 2. set_vf_spoofchk - disallowed 3. set_vf_mac - allowed 4. get_vf_config - allowed 5. set_vf_trust - disallowed 6. set_vf_rate - disallowed 7. get_vf_stat - allowed 8. set_vf_link_state - disallowed Fixes: f942380c1239 ('net/mlx5: E-Switch, Vport ingress/egress ACLs rules for spoofchk') Signed-off-by: Eli Cohen <eli@mellanox.com> Reviewed-by: Or Gerlitz <ogerlitz@mellanox.com> Tested-by: Or Gerlitz <ogerlitz@mellanox.com>
