Rhel Kernel version information:

Check the driver, manufacturer and other information of the NIC:

[Email protected] ~]# kudzu--probe--class=network-class:networkbus:pcidetached:0device:eth0driver:r8169--------- -------> This is the driver name, the following Modinfo command uses the driver name.

Here's how fast the network card is viewed:

As the following command can be seen is not integrated network card? ---yet to be verified.

[Email protected] ~]# Dmidecode | Sed-n '/net/,+5p '        type:ethernet        status:enabled        Description:  Onboard Ethernet  --------------- ----> Does this mean that this is an integrated NIC? If you have a chance, get a PCI NIC, and then execute this command to see what the output is. Handle 0x0020, DMI type one, 5 bytesoem Strings

The following command also shows the manufacturer information for the NIC Controller.
