NOTE: stable/2024.2 only, as this is a combination of two commits in one to not introduce a regression by doing them separately. There were small changes required to unit tests as the code had changed in 2025.1 where this was originally merged. First commit: If the configuration option "ovn.ovn_emit_need_to_frag" is set, write always the "LSP.options.gateway_mtu" value, using the minimum MTU value of all networks connected to the router. That will limit the N/S traffic MTU regardless if the gateway network MTU is greater or less than the internal network MTU. Conflicts: neutron/plugins/ml2/drivers/ovn/mech_driver/ovsdb/ovn_client.py neutron/tests/functional/plugins/ml2/drivers/ovn/mech_driver/ovsdb/test_ovn_client.py neutron/tests/unit/services/ovn_l3/test_plugin.py (cherry picked from commitd080b35782) Second commit: Revert the network IDs filter in ``_gen_router_port_options`` In [1], a change in the ``network_ids`` filter was introduced. This filter is used to retrieve the networks belonging to a router. However this is used in two places: * To set the gateway MTU. Here all the networks attached to the router must be present. * To calculate the "redirect-type" value in the Logical_Router_Port. Only the internal interfaces must be present; the gateway port should be discarded. NOTE: patch [1] is present since 2025.1 (Epoxy).
