SRIOV VFs used in macvtap passthrough mode can take advantage of the SRIOV card's transparent vlan tagging. All the code was there to set the vlan tag, and it has been used for SRIOV VFs used for hostdev interfaces for several years, but for some reason, the vlan tag for macvtap passthrough devices was stubbed out with a -1. This patch moves a bit of common validation down to a lower level (virNetDevReplaceNetConfig()) so it is shared by hostdev and macvtap modes, and updates the macvtap caller to actually send the vlan config instead of -1.
