Comment 5 for bug 1889454

Hello:

As Darragh commented, when a bridge is created, a port with type=internal is created. Because we are not sending or receiving traffic from this port, why do we need to care about those log messages?

Are your VMs dropping traffic because the MTU is too low? Do you have problems setting the Neutron MTU config? Remember there are several parameters to define: global_physnet_mtu, physical_network_mtus, segment_mtu, path_mtu.
