Provides the option to set the "ovn_emit_need_to_frag" configuration
option to the "ovn" section of etc/neutron/plugins/ml2_conf.ini. This
option tells ovn whether it should emit ICMP "need to frag" packets
in case of MTU mismatch. Before enabling this configuration make
sure that it's 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.
