You might have seen some systems using Ethernet interface names like "<code>enp0s3</code>" instead of the traditional "<code>ethN</code>" nomenclature. Here is what they mean:

$ ls -l /sys/class/net/
lrwxrwxrwx. 1 root root 0 Oct 23 21:42 enp0s3 -> ../../devices/pci0000:00/0000:00:03.0/net/enp0s3
lrwxrwxrwx. 1 root root 0 Oct 23 21:42 enp0s8 -> ../../devices/pci0000:00/0000:00:08.0/net/enp0s8
lrwxrwxrwx. 1 root root 0 Oct 23 21:42 enp0s9 -> ../../devices/pci0000:00/0000:00:09.0/net/enp0s9

$ lspci |grep -i net
00:03.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
00:08.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
00:09.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)

So, "<code>enp0s3</code>" => Ethernet network peripheral #0 on serial port #3. PCI bus numbers will be in order: 3, 8, 9, a(10). Or, 3 = NIC#1, 8 = NIC#2, etc.

$ lshw -C network
...
bus info: pci@0000:00:03.0
logical name: enp0s3
...

$ lspci|grep -i net
00:03.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)

The first characters of each line are in the format: <code>[<bus>]:[<slot>].[<func>]</code>

In the above example, the bus is 0x00, the slot is 0x03, and the function is 0x0, where:
;bus : the bus of the PCI device
;slot : the slot of the PCI device
;function : the function of the PCI device
