description:
  Portals are memory mapped interfaces to QMan that allow low-latency, lock-less
  interaction by software running on processor cores, accelerators and network
  interfaces with the QMan

    description:
      The hardware index of the channel. This can also be
      determined by dividing any of the channel's 8 work queue
      IDs by 8

      In addition to these properties the qman-portals should have sub-nodes to
      represent the HW devices/portals that are connected to the software portal
      described here
