Comment 7 for bug 1785189

Thanks for detailed report.
So You are suggesting that increase of hardcoded mtu=64kbit for filters in l3_tc_lib: https://github.com/openstack/neutron/blob/master/neutron/agent/linux/l3_tc_lib.py#L120 up to e.g. 80kb should help to solve that issue? Am I understand correct You?
