 * Starting with Win8, we can statically distribute the incoming

 * We do this in a hierarchical fashion:

 * First distribute the primary channels across available NUMA nodes

 * and then distribute the subchannels amongst the CPUs in the NUMA

 * node assigned to the primary channel.

 * We distribute the interrupt loads to one or more NUMA nodes based on

 * the channel's affinity_policy.

 * For pre-win8 hosts or non-performance critical channels we assign the

 * first CPU in the first NUMA node.
