[libvirt] [PATCH 4/7] virNetDevBandwidthSet: Add priority to filter

[Michal Privoznik]

Currently, when constructing traffic shaping rules, the ingress
filter is created without any priority specified on the command
line. This makes kernel to make up one. While this works, it
simplifies things a big if we provide the filter priority. In
this case, since it's the root filter lets have it the highest
priority of number 1.
