voidrte_pci_device_name(conststructrte_pci_addr*addr,char*output,size_tsize)
       Utility function to write a pci device name, this device name can later be used to retrieve the
       corresponding rte_pci_addr using rte_pci_addr_parse().

       Parametersaddr The PCI Bus-Device-Function address
           output The output buffer string
           size The output buffer size

   intrte_pci_addr_cmp(conststructrte_pci_addr*addr,conststructrte_pci_addr*addr2)
       Utility function to compare two PCI device addresses.

       Parametersaddr The PCI Bus-Device-Function address to compare
           addr2 The PCI Bus-Device-Function address to compare

       Returns
           0 on equal PCI address. Positive on addr is greater than addr2. Negative on addr is less than addr2,
           or error.

   intrte_pci_addr_parse(constchar*str,structrte_pci_addr*addr)
       Utility function to parse a string into a PCI location.

       Parametersstr The string to parse
           addr The reference to the structure where the location is stored.

       Returns
           0 on success <0 otherwise
