[libvirt] [PATCH] Remove macvtap dependancy on domain configuration

Wed Jun 22 15:45:13 UTC 2011
Files under src/util must not depend on src/conf
Solve the macvtap problem by moving the definition
of macvtap modes from domain_conf.h into macvtap.h
* src/util/macvtap.c, src/util/macvtap.h: Add enum
for macvtap modes
* src/conf/domain_conf.c, src/conf/domain_conf.h: Remove
enum for macvtap modes
