Bug Description
With neutron-api physical-
DPDK interfaces on neutron-openvswitch hosts only have 1500:
for x in `ovs-vsctl list-ifaces br-data | head -n2`; do ovs-vsctl get Interface $x mtu; done
1500
1500
This is proven out by running ping -s 8000 across compute nodes:
ping -Mdo -s 8000 172.20.0.4
PING 172.20.0.4 (172.20.0.4) 8000(8028) bytes of data.
^C
--- 172.20.0.4 ping statistics ---
