Linux does not have the hardware driver, how to find the driver it. A fiber-optic card, for example, is not driven.
First of all, to obtain LSPCI information, know the relevant information of fiber card
Root@localhost/]# Lspci
0e:00.0 Fibre channel:qlogic Corp.: Unknown Device 2432 (rev 03)
|
This unknow device is a fiber-optic card Fibre Channel, and a QLogic fiber-optic card. The previous hardware ID needs to know 0e:00.0.
Then use the LSPCI-NV parameter to continue fetching information
| [Root@localhost/]# LSPCI-NV
0e:00.0 Class 0c04:1077:2432 (rev 03)

From the 0e:00.0 can be determined that the fiber card information is the above section, where the total need is "1077:2,432".
In the system there is a file/usr/share/hwdata/pcitable, which holds all the supported and unsupported hardware information for this system. 1077 of them represent the manufacturer qlogic,2432 is the model of the card.
Well, now I have a driver package, there are many modules, in the end whether the module in this package supports this card. Exactly which module supports this card?
