[libvirt] [PATCH 03/27] network: pass a virNetworkPtr to port management APIs
Daniel P. Berrangé
berrange at redhat.com
Mon Dec 24 14:58:51 UTC 2018
The APIs for allocating/notifying/removing network ports just take
an internal domain interface struct right now. As a step towards
turning these into public facing APIs, add a virNetworkPtr argument
to all of them.
