In 35a331a9 we added a new API that enables peer-2-peer (P2P) copies between NVMe SSDs using Controller Memory Buffers (CMBs) that support DMA operations. Add documentation for the API, the example application (cmb_copy) and for P2P setup and operation. Note that this new API is currently marked experimental.
