[libvirt] [PATCH 17/33] Remove ifaceSetMac and ifaceGetMac APIs
Daniel P. Berrange

Thu Nov 3 17:30:13 UTC 2011
From: "Daniel P. Berrange" <berrange at redhat.com>
The ifaceSetMac and ifaceGetMac APIs duplicate the functionality
of the virNetDevSetMAC and virNetDevGetMAC APIs, but returning
errno's instead of raising errors.
* src/util/interface.c, src/util/interface.h: Remove
ifaceSetMac and ifaceGetMac APIs, adjusting callers
for new error behaviour
