Format is pci<slot>#<port>. [...] I tried this on a Supermicro board here, which doesn't have this information. eth0 and eth1 are LOM ports, eth2 and eth3 are on a NIC. The debug output is: BIOS device: Kernel name: eth2 Assigned MAC : 00:0F:53:01:41:14 Driver: sfc Driver version: 3.0 Firmware version: 3.0.8.2217 Bus Info: 0000:01:00.0 PCI name : 0000:01:00.0 PCI Slot : Unknown Index in slot: 7 BIOS device: Kernel name: eth3 Assigned MAC : 00:0F:53:01:41:15 Driver: sfc Driver version: 3.0 Firmware version: 3.0.8.2217 Bus Info: 0000:01:00.1 PCI name : 0000:01:00.1 PCI Slot : Unknown Index in slot: 8 BIOS device: Kernel name: eth0 Permanant MAC: 00:30:48:90:81:9E Assigned MAC : 00:30:48:90:81:9E Driver: e1000e Driver version: 1.2.7-k2 Firmware version: 0.15-4 Bus Info: 0000:0d:00.0 PCI name : 0000:0d:00.0 PCI Slot : Unknown Index in slot: 9 BIOS device: Kernel name: eth1 Permanant MAC: 00:30:48:90:81:9F Assigned MAC : 00:30:48:90:81:9F Driver: e1000e Driver version: 1.2.7-k2 Firmware version: 0.5-7 Bus Info: 0000:0e:00.0 PCI name : 0000:0e:00.0 PCI Slot : Unknown Index in slot: 10 It appears that 'unknown slot' is treated as a specific slot and all devices with an unknown slot are given unique indices. Perhaps this doesn't matter in the end, since no name is generated when the slot is unknown. However, the 2 NIC ports do have their own indices (specified with the dev_id attribute) and it should be possible to distinguish slots by PCI/PCIe topology even though the name given won't correspond to any markings on the motherboard.
