+#  (optional) A list of key-value pairs that map a chassis specific mac to
+#  a physical network name. An example
+#  value mapping two chassis macs to two physical network names would be:
+#  physnet1:aa:bb:cc:dd:ee:ff,physnet2:a1:b2:c3:d4:e5:f6
+#  These are the macs that ovn-controller will replace a router port
+#  mac with, if packet is going from a distributed router port on
+#  vlan type logical switch.
+#  Defaults to hiera('ovn_chassis_mac_map')
