category: bugfix
bugzilla: 4472

-----------------------------------------------------------------------

When using the ip link command to configure the MAC for the VF in the
PF, the status 4 will be returned when the MAC is set on the VF; when
the PF driver receives the status 4 returned by the firmwre, the MAC
setting failed and an error should be reported.
