[ Upstream commit ca36fc4d77b35b8d142cf1ed0eae5ec2e071dc3c ]
E-switch should be able to set the GUID of host PF vport. Currently it returns an error. This results in below error when user attempts to configure MAC address of the PF of an external controller.
$ devlink port function set pci/0000:03:00.0/196608 \ hw_addr 00:00:00:11:22:33
mlx5_core 0000:03:00.0: mlx5_esw_set_vport_mac_locked:1876:(pid 6715):\ "Failed to set vport 0 node guid, err = -22. RDMA_CM will not function properly for this VF."
Check for zero vport is no longer needed.
