This article mainly introduces how to determine the driver used by the network card under Linux. It is very detailed and has a certain reference value. Interested friends must read it!

1. Whether it is an integrated network card or an independent network card, it must be connected to the PCI bus in some way, so there must be a code name.

This code name can be obtained with the following command

# lspci | grep Ethernet

02Rod 00.0 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01)

The foremost "02 rig 00.0" is the code name of the device on the PCI bus, which is unique in the whole system.

two。 After getting the PCI code of the network card, we can find its driver in sysfs, as follows

# cd / sys/bus/pci/drivers

# find | grep '02purl 00.0'

. / e1000e/0000:02:00.0

3. Through the above command, we can find that the device is under the "e1000e" folder, that is to say, the driver of the network card is e1000e

4. In summary, on the Linux system, the command to find the driver being used by the network card is as follows

# code=$ (lspci | grep Ethernet | head-1 | awk'{print $1}')

# find / sys/bus/pci/drivers/ | grep $code | awk-F /'{print $6}'

Or

# find / sys/bus/pci/drivers/ | grep $(lspci | grep Ethernet | head-1 | awk'{print $1}') | awk-F /'{print $6}'
