+         or Xilinx Dynamic Function eXchnage AIX Shutdown Manager.
          The PR Decoupler exists in the FPGA fabric to isolate one
          region of the FPGA from the busses while that region is
          being reprogrammed during partial reconfig.
+         The Dynamic Function eXchange AXI shutdown manager prevents
+         AXI traffic from passing through the bridge. The controller
+         safely handles AXI4MM and AXI4-Lite interfaces on a
+         Reconfigurable Partition when it is undergoing dynamic
+         reconfiguration, preventing the system deadlock that can
+         occur if AXI transactions are interrupted by DFX.
