Dp2pdma.rst49 in that it exposes any CMB (Controller Memory Buffer) as a P2P memory
51 to be used directly (client) and it can also make use of the CMB as
56 to the P2P memory (CMB) and then to the NVMe device (and vice versa).
62 then the NVMe Target could use the RNIC's memory instead of the CMB
63 in cases where the NVMe cards in use do not have CMB support.
