commit fc7b23db switched from using ioctl(SIOCBRADDBR) for bridge creation to using a netlink RTM_NEWLINK message with IFLA_INFO_KIND = "bridge", which is the more modern way to create a bridge. However, although older kernels (e.g. 2.6.32, in RHEL6/CentOS6) support creating *some* link types with RTM_NEWLINK, they don't support creating bridges, and there is no compile-time way to figure this out (since the "type" isn't an enum, but rather a character string). This patch moves the body of the SIOCBRADDBR version of virNetDevBridgeCreate() into a static function, calls the new function from the original, and also calls the new function from the RTM_NEWLINK version if the RTM_NEWLINK message generates an EOPNOTSUPP error.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
