I am confused regarding the NIC I am using. Could somebody help me with that?

I am using Centos 7. When I do lspci i get the following result:

Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 07)

  1. What is [10ec:8168].
  2. Is this NIC different from RTL8111B or RTL8168B?
  3. Am I using RTL8168B or RTL8168g or any other version? How can I check the exact version?
  4. Are MAC/Phy register offsets and configuration offsets different for different versions of RTL8168?

  • Welcome to Unix and Linux. 1 ) 10ec is the vendor (Realtek), 8168 is the device ID 2) Gigabit ethernet pci-ids.ucw.cz/read/PC/10ec/8168 3) They use the same ID, they must have some slight differences 4) Question is off-topic per our FAQ. Google it. – Rui F Ribeiro Oct 28 '16 at 9:33

    Thank you for your reply. The version of NIC that I have is not supported by a particular driver(powerlink), however RTL8168B is supported. So, I would like to know the difference in the two hardwares (RTL8168 and RTL8168b). Would you help me with that? I found the datasheet for RTL8168b but not RTL8168. – user3094049 Oct 28 '16 at 10:24
