this is slightly overbroad, since no one said that the net-dimm has to
implement a flat addressing scheme. that is, that the only addressing bits
come from the normal row/col addresses used in the standard dram protocol.
suppose, for instance, row/col merely selected the destination node, and the
first 64 bits of the data burst defined the memory address (in the destination
node's address space).
