Title:
  Neutron agents do not use network MTU

Status in networking-midonet:
  In Progress
Status in neutron:
  Fix Released

Bug description:
  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.
