Hi Nicole.Z
Further checking ,the adminstrator set VF MAC address then later on Network Manager tried to set VF MAC address that was disallowed then VF has to be reset. Since Intel PF and VF drivers has a built in security feature called administrative assignment of VF MAC address. If the server administrator assigns a VF MAC address from the HOST any subsequent changes to the VF MAC address are disallowed.
Thus please try disabling the network manager.
