libvirt was unconditionally calling virNetDevBandwidthClear() for every interface (and network bridge) of a type that supported bandwidth, whether it actually had anything set or not. This doesn't hurt anything (unless ifname == NULL!), but is wasteful. This patch makes sure that all calls to virNetDevBandwidthClear() are qualified by checking that the interface really had some bandwidth setup done, and checks for a null ifname inside virNetDevBandwidthClear(), silently returning success if it is null (as well as removing the ATTRIBUTE_NONNULL from that function's prototype, since we can't guarantee that it is never null, e.g. sometimes a type='ethernet' interface has no ifname as it is provided on the fly by qemu).
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.
