commit 46ddaf4288a1cac44d8afc0525b4ecb3ae2186a3

    Allow to use several nics for physnet with SR-IOV
    
    Accordind specs and docs, SRIOV_NIC.physical_device_mappings is not
    limited to be a 1-1 mapping between physnets and NICs. However,
    implementation requires this. This bugfix unlocks 1-M mappings, so one
    physnet could be managed by many NICs.
    
    * introduced unique_keys in neutron.utils.parse_mappings
    * SRIOV_NIC.physical_device_mappings is parsed as dict with lists as
      values with parse_mappings(..., unique_keys=False)

Title:
  [sriov] physical_device_mappings allows only one physnet for per nic

Status in neutron:
  Fix Released

Bug description:
  Mitaka, ML2, ml2_sriov.agent_required=True

  sriov_nic.physical_device_mappings is allowed to specify ony one NIC
  per physnet. If I try to specify two nics like following

  [sriov_nic]
  physical_device_mappings=physnet2:enp1s0f0,physnet2:enp1s0f1

  I've got next error on start
