I have a basic question regarding pci 16-bit field addresses. I got the following output from 'lspci' command.
02:00.0 CardBus bridge: Texas Instruments PCI1520 PC card Cardbus Controller (rev 01)
02:00.1 CardBus bridge: Texas Instruments PCI1520 PC card Cardbus Controller (rev 01)
02:01.0 Ethernet controller: Intel Corp. 82540EP Gigabit Ethernet Controller (Mobile) (rev 03)
02:02.0 Network controller: Intel Corp. PRO/Wireless LAN 2100 3B Mini PCI Adapter (rev 04)
I have a IBM thinkpad t40 laptop with built-in ethernet card. I see that CardBus Bridge has a bus number of 2 and My ethernet controller also has a bus number 2. Does that mean that my ethernet card is Cardbus device?
