+# This example script creates bonding network devices based on synthetic NIC
+# (the virtual network adapter usually provided by Hyper-V) and the matching
+# VF NIC (SRIOV virtual function). So the synthetic NIC and VF NIC can
+# function as one network device, and fail over to the synthetic NIC if VF is
+# down.
+#
+# Usage:
+# - After configured vSwitch and vNIC with SRIOV, start Linux virtual
+#   machine (VM)
+# - Run this scripts on the VM. It will create configuration files in
+#   distro specific directory.
+# - Reboot the VM, so that the bonding config are enabled.
+#
+# The config files are DHCP by default. You may edit them if you need to change
+# to Static IP or change other settings.
