a network resource, why we need to filter the assignable

this it for the Neutron SRIOV, a physical netowrk is a attribute
added to a pci device. if you want allocated a nic from pci, you
must ensure we get a PCI device which does connect to the correct
physical network as same as Neutron defined. <br>

yes. but not mean the pci_flavor is separated from normal flavor,
the flavor is the original alias with api support. we rename to
pci_flavor because it's just for pci and the flaovr things much more
OS style.<br>
<br>
hope help you.<br>
