PvmVnicSriovVifDriver, a VIF driver for vNICs backed by SR-IOV VFs. The
main plug method intercepts incoming vif requests and branches off to
this new vif driver if the vif type is 'pvm_sriov'. The driver "plugs"
a new vNIC into the instance by:
- Building a new pypowervm.wrappers.iocard.VNIC object.
- Assigning backing devices from the pool of physical ports labeled
according to the physical network name.
- Creating the VNIC on the PowerVM REST server as a child of the LPAR
corresponding to the instance.
The unplug method locates the appropriate VNIC according to its MAC
address and deletes it from the PowerVM REST server.
