i am using large mtu setting of 9000. with the hybrid firewall driver i see large mtu set on both tap devices and the linuxbridges
While i switch from ovs hybrid firewall driver to native ovs firewall driver i now see the tap device gets the default 1500 mtu
i have the right setting for mtu in global physnet mtu in neutron.conf and path mtu in ml2 conf
Do i need to do anything different to get large mtu working with native ovs firewall driver
