+# Intel FPGA  device plugin

+# and

+#
+# The following modifications have been made:
+#  - A nodeSelector of 'intelfpga' has been added to ensure the fpga device plugin
+#   pods only run on appropriately labelled nodes.
+#  - The daemonset is modified to tolerate all NoSchedule taints
+#  - A initContainers clause has been removed. The intel-fpga-initcontainer,
+#  that reprogramm FPGA on a container's startup, only works with CRI-O.
