Public bug reported:

The Neutron agents do not use the MTU set in the network object for
their interfaces. This prevents the L3 and DHCP agents from being
compatible with networks with jumbo frames and it causes them to
transmit packets larger than the network's MTU onto the network where
they will be dropped instead of correctly fragmenting, generating an
ICMP error; or, in the case of the DHCP agent, reducing the MSS for its
traffic.
