    Fix bulk create without mac
    
    Bulk port create without mac address fails as when Neutron calls
    oslo_utils.netutils.get_ipv6_addr_by_EUI64, as the mac field of the port
    is an ATTR_NOT_SPECIFIED Sentinel() object.
    With some reshuffling of the code to fill the mac field this can be
    fixed.

Title:
  bulk port create: TypeError: Bad prefix type for generating IPv6
  address by EUI-64

Status in neutron:
  Fix Released

Bug description:
  source openrc admin admin
  export TOKEN="$( openstack token issue -f value -c id )"

  A single port create succeeds:
  curl -s -H "Content-Type: application/json" -H "X-Auth-Token: $TOKEN" -d "{\"port\":{\"name\":\"port0\",\"network_id\":\"$( openstack net show private -f value -c id )\"}}" -X POST http://127.0.0.1:9696/networking/v2.0/ports | json_pp
  ...

  But the same request via the bulk api fails:
  curl -s -H "Content-Type: application/json" -H "X-Auth-Token: $TOKEN" -d "{\"ports\":[{\"name\":\"port0-via-bulk\",\"network_id\":\"$( openstack net show private -f value -c id )\"}]}" -X POST http://127.0.0.1:9696/networking/v2.0/ports | json_pp
  {
     "NeutronError" : {
        "detail" : "",
        "message" : "Request Failed: internal server error while processing your request.",

  }

  While in q-svc logs we have:
