Sometimes if a newly developed PCIE device (for example，Wangxun WX1860  Ethernet controller) is loacted on your system, you may see "lspci" cannot show its vendor and device name and replaced with its vendor ID and device ID.

18:00.0 Ethernet controller: Device 8088:0107 (rev 01)
18:00.1 Ethernet controller: Device 8088:0107 (rev 01)
18:00.2 Ethernet controller: Device 8088:0107 (rev 01)
18:00.3 Ethernet controller: Device 8088:0107 (rev 01)

This is because the vendor ID and device ID is not included in the pci.ids file, so "lspci" cannot translates it into vendor and device name. You may download the latest pci.ids file from the following hyperlink and replace the old one in your linux.

https://pci-ids.ucw.cz/

The old pci.ids file can be found by the following command.

# find / -name pci.ids

After update the pci.ids file, then you can get the vendor and device name now.
