Re: [libvirt] [PATCH 2/2 V2] cleanup: make several interface functions commonly available

In a second cleanup step this patch makes several interface functions from macvtap.c commonly available by moving them into interface.c and prefixing their names with 'iface'. ifaceRestoreMacAddress returns the return code from the ifaceSetMacAddres call and display an error message if setting the MAC address did not work. The caller is unchanged and still ignores the return code (which is ok). This patch also fixes a problem with the return code of ifaceSetMacAddress being used for error reporting in one place rather than errno. v2: - making all functions visible on all platforms Signed-off-by: Stefan Berger <stefanb(a)linux.vnet.ibm.com&gt;
