Thu Nov 3 17:30:12 UTC 2011
From: "Daniel P. Berrange" <berrange at redhat.com>
The ifaceUp, ifaceDown, ifaceCtrl & ifaceIsUp APIs can be replaced
with calls to virNetDevSetOnline and virNetDevIsOnline
* src/util/interface.c, src/util/interface.h: Delete ifaceUp,
ifaceDown, ifaceCtrl & ifaceIsUp
* src/nwfilter/nwfilter_gentech_driver.c, src/util/macvtap.c:
Update to use virNetDevSetOnline and virNetDevIsOnline
