This patch is adding a new configuration option called
"ovn_emit_need_to_frag" to be set in the "ovn" section of
etc/neutron/plugins/ml2_conf.ini.
When set to True the 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.
This option was intruced by networking-ovn at:
