+    Add a new configuration option called "ovn_emit_need_to_frag" to
+    the "ovn" section of etc/neutron/plugins/ml2_conf.ini. This new
+    option tells ovn whether it should emit "need to frag" packets
+    in case of MTU mismatch. Before enabling this configuration make
+    sure that its supported by the host kernel (version >= 5.2) or
+    by checking the output of the following command: ovs-appctl -t
+    ovs-vswitchd dpif/show-dp-features br-int | grep "Check pkt length
+    action". Defaults to False.
