+Arkville RTL Core Configurations
+-------------------------------------
+
+Arkville's RTL core may be configured by the user for three different
+datapath widths to balance throughput against FPGA logic area. The ARK PMD
+has introspection on the RTL core configuration and acts accordingly.
+All three configurations present identical RTL user-facing AXI stream
