/*

* Predictable network interface device names based on:

* - firmware/bios-provided index numbers for on-board devices

* - firmware-provided pci-express hotplug slot index number

* - physical/geographical location of the hardware

* - the interface’s MAC address

*

* http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames

*

* Two character prefixes based on the type of interface:

* en – ethernet

* sl – serial line IP (slip)

* wl – wlan

* ww – wwan

*

* Type of names:

* b – BCMA bus core number

* ccw – CCW bus group name

* o[d] – on-board device index number

* s[f][d] – hotplug slot index number

* x – MAC address

* [P]ps[f][d]

* – PCI geographical location

* [P]ps[f][u][..][c][i]

* – USB port number chain

*

* All multi-function PCI devices will carry the [f] number in the

* device name, including the function 0 device.

*

* When using PCI geography, The PCI domain is only prepended when it is not 0.

*

* For USB devices the full chain of port numbers of hubs is composed. If the

* name gets longer than the maximum number of 15 characters, the name is not

* exported.

* The usual USB configuration == 1 and interface == 0 values are suppressed.

*

* PCI ethernet card with firmware index “1”:

* ID_NET_NAME_ONBOARD=eno1

* ID_NET_NAME_ONBOARD_LABEL=Ethernet Port 1

*

* ID_NET_NAME_MAC=wwx028037ec0200

* ID_NET_NAME_PATH=wwp0s29u1u4i6

*

* USB Android phone:

* /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/net/enp0s29u1u2

* ID_NET_NAME_MAC=enxd626b3450fb5

enp0s10:

en – ethernet

p0 – bus number (0)

s10 -- slot number (10)
