Since Mitaka, Neutron does the right job, calculating MTU for networks and advertising them thru DHCP and RA. 1. Don't disable MTU advertisement in neutron.conf (advertise_mtu). 2. Don't disable MTU calculation (path_mtu = 0, segment_mtu = 0). 3. Don't set network_device_mtu (it breaks data path and is deprecated). Change-Id: I28536c5a13711c8e82d056fb47567234aab4e547
