Claim: Solaris network virtualization and resource control (developed by  Sun Microsystems) can have more than one VNIC which operates as a physical NIC, it also has a MAC address.
Evidence: Solaris network virtualization and resource control is a set of features originally developed by Sun Microsystems as the OpenSolaris Crossbow umbrella project, providing an internal network virtualization and quality of service framework within the Solaris Operating System. A physical interface can have more than one VNIC. Each VNIC operates like and appears to the system as a physical NIC. The individual VNIC is assigned a media access control address (MAC address), which can be configured to a value other than the default MAC address assigned to the physical NIC.
