- function_id
  A zPCI function identifier that uniquely identifies the function in the Z server.

  Low-level identifier used for a configured PCI function.
  It might be useful for debugging.

- pchid
  Model-dependent location of the I/O adapter.

- pfgid
  PCI function group ID, functions that share identical functionality
  use a common identifier.
  A PCI group defines interrupts, IOMMU, IOTLB, and DMA specifics.

  The virtual function number, from 1 to N for virtual functions,
  0 for physical functions.

- pft
  The PCI function type

- port
  The port corresponds to the physical port the function is attached to.
  It also gives an indication of the physical function a virtual function
  is attached to.

- uid
  The user identifier (UID) may be defined as part of the machine
  configuration or the z/VM or KVM guest configuration. If the accompanying
  uid_is_unique attribute is 1 the platform guarantees that the UID is unique
  within that instance and no devices with the same UID can be attached

- uid_is_unique
  Indicates whether the user identifier (UID) is guaranteed to be and remain
  unique within this Linux instance.

- pfip/segmentX
  The segments determine the isolation of a function.
  They correspond to the physical path to the function.
  The more the segments are different, the more the functions are isolated.
