Title:
  Change the default value of "propagate_uplink_status" to True

Status in neutron:
  Fix Released

Bug description:
  RFE [1] implemented a new port extension for SR-IOV ports. When this
  extension is enabled, the user can set this new flag
  "propagate_uplink_status" to True. That will set the VF link-state
  associated to this SR-IOV to "auto".

  By default, without this extension, the link-state will be set to
  "enable" or "disable".

  With this extension and "propagate_uplink_status" to False, the
  behavior will be the same ("enable"/"disable").

  This bug is proposing to, by default, if this extension is enabled, to
  set "propagate_uplink_status" to True. That will set the link-state of
  the VF to "auto". That means the VF state will follow the PF state

  NOTE: in some devices, the VF set to "enable" can transmit traffic
  when the PF is "down". That means if the VF is set to "auto", the VF
  won't be able to transmit. But, IMO, this behavior is more reasonable
  that allowing the VF to use the line when the PF is down.
