  This's a temporary workaround for adding this option
  "log_num_mgm_entry_size=-1" to /etc/modprobe.d/mlx4.conf file in order to
  allow steering in ConnectX-3 devices


resources:
  userdata:
    type: OS::Heat::MultipartMime
    properties:
      parts:
      - config: {get_resource: allow_steering}
  allow_steering:
    type: OS::Heat::SoftwareConfig
    properties:
      config: |
        #!/bin/bash
        set -x
        echo "options mlx4_core log_num_mgm_entry_size=-1" >> /etc/modprobe.d/mlx4.conf
        /sbin/dracut --force

outputs:
  # This means get_resource from the parent template will get the userdata, see:
  # http://docs.openstack.org/developer/heat/template_guide/composition.html#making-your-template-resource-more-transparent
  # Note this is new-for-kilo, an alternative is returning a value then using
  # get_attr in the parent template instead.
