The main fix here is Patch 1, which adds the code necessary to support
live update of the vlan tag for a direct (macvtap) passthrough
interface, thus resolving two separate issues. The other three are
just small annoyances that I found while testing.

Laine Stump (4):
  qemu: update vlan tag of macvtap (direct) passthrough devices during
    update-device
  qemu: use actual/effective vlan when updating OVS-based interface vlan
    tag
  conf: validate that specified interface type supports vlan tags
  conf: simplify check for vlan tagging support in
    virDomainActualNetDefValidate()
