That card must be very new. It's not supported by either CentOS 7 or 8 though it is by Fedora 32. Perhaps check back when CentSO 8.2 comes out soon.

Claims that vanilla 5.5 kernel supports that card and that Ubuntu has backported to their 5.3 kernel.

Intel's page about I219-V shows quite a life expectancy. Launch Date: Q2'15; Expected Discontinuance: 1H'30
There must be many ID's covered by the model name.

Hi

I've tried also Install Ubuntu 20.04, ethernet card is shown but it connect and disconnect continuously.

I managed to solve problem. I've installed e1000e-3.8.4.tar.gz from intel download page https://downloadcenter.intel.com/downlo ... 8.4.tar.gz and it works.

So, thanks everyone, for replies.

That will break as soon as the next kernel update gets installed. You'll have to repeat that install for each and every kernel update.

You should raise a ticket on bugzilla.redhat.com to report the lack of support. You could also try asking ELRepo if they could package the latets driver as a kmod. Raise an enhancement request (RFE) on their bugtracker to ask.

TrevorH thanks for suggestion.
Bug reported 1840601, and Their reply
Looks like this should be supported by kernel-4.18.0-147.13.el8 and later.

I know, but it was only chance to get it worked immediately.

Ok, so it'll be in 8.2 then.
