52   The slot entries are set up using the function identifier (FID) of the
53   PCI function.

63   - function_id
64     A zPCI function identifier that uniquely identifies the function in the Z server.
66   - function_handle
67     Low-level identifier used for a configured PCI function.
70   - pchid
71     Model-dependent location of the I/O adapter.
73   - pfgid
74     PCI function group ID, functions that share identical functionality
78   - vfn
79     The virtual function number, from 1 to N for virtual functions,

83     The PCI function type

86     The port corresponds to the physical port the function is attached to.

95     The segments determine the isolation of a function.
96     They correspond to the physical path to the function.
102 The PCI address consists of four parts: domain, bus, device and function,
105 * When not using multi-functions (norid is set, or the firmware does not
106   support multi-functions):
108   - There is only one function per domain.
110   - The domain is set from the zPCI function's UID as defined during the

116   - There is still only one bus per domain.
118   - There can be up to 256 functions per bus.
120   - The domain part of the address of all functions for
121     a multi-Function device is set from the zPCI function's UID as defined
122     in the LPAR creation for the function zero.
124   - New functions will only be ready for use after the function zero
125     (the function with devfn 0) has been enumerated.
