Subject: net/mlx5: E-Switch, Allow setting GUID for host PF vport
Patch-mainline: v5.13-rc7
Git-commit: ca36fc4d77b35b8d142cf1ed0eae5ec2e071dc3c
References: jsc#SLE-15172
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.
Fixes: 330077d14de1 ("net/mlx5: E-switch, Supporting setting devlink port function mac address")
