[libvirt] [PATCH 07/16] network: Alter virNetworkObj @class_id to be @classIdMap
John Ferlan

Fri May 19 13:03:15 UTC 2017
Change the variable name to be a bit more descriptive and less confusing
when used with the data.network.actual->class_id.
In preparation for privatizing virNetworkObj, create accessor function to
fetch the @classIdMap.
