[libvirt] [PATCH 02/16] Rename and split the macvtap.c file
Daniel P. Berrange

Tue Nov 15 11:14:15 UTC 2011
From: "Daniel P. Berrange" <berrange at redhat.com>
Rename the macvtap.c file to virnetdevmacvlan.c to reflect its
functionality. Move the port profile association code out into
virnetdevvportprofile.c. Make the APIs available unconditionally
to callers
* src/util/macvtap.h: rename to src/util/virnetdevmacvlan.h,
* src/util/macvtap.c: rename to src/util/virnetdevmacvlan.c
* src/util/virnetdevvportprofile.c, src/util/virnetdevvportprofile.h:
Pull in vport association code
* src/Makefile.am, src/conf/domain_conf.h, src/qemu/qemu_conf.c,
src/qemu/qemu_conf.h, src/qemu/qemu_driver.c: Update include
paths & remove conditional compilation
