Get the CPU set of logical processors that are physically close to device
Return the CPU set describing the locality of the OpenFabrics device
topology and device
ibdev must match the local machine. I/O devices detection is not needed in the topology.
The function only returns the locality of the device. If more information about the device is needed, OS objects should be used instead, see hwloc_ibv_get_device_osdev() and hwloc_ibv_get_device_osdev_by_name().
This function is currently only implemented in a meaningful way for Linux; other systems will simply get a full cpuset.
