How to create a network connection for Atheros Killer E2400 hardware

I'm working on moving a working server based on Centos 6.10 (Final) that is running on old Core 2 Duo hardware to a newer i3 box. The only hold-up right now is that integrated ethernet hardware the new box is based on Atheros Killer 2400 which Centos 6 does not support - yes, I know that Centos 7 does support it but porting all the configured services is more than I want to do at this time. I have tried installing the kmod-alx but still the ethernet hardware is ignored. How do I make Centos aware of it so that the etho is created or would I go about manually creating whatever config is required to activate this ethernet connection?

Thanks

What is the output from lspci -nn | grep -i net

It tells me:
$ lspci -nn | grep -i net
02:00.0 Ethernet controller [0200]: Qualcomm Atheros Killer E2400 Gigabit Ethernet Controller [1969:e0a1] (rev 10)

And according to my research I installed kmod-alx that supposedly knows about it (but does not appear to):
$ rpm -q kmod-alx
kmod-alx-0.0-10.el6.elrepo.x86_64

Thank you for any advise!

Your version of the card is not supported by anything in the distro as can be seen by running

Code: Select all

[trevor@c6test ~]$ grep -i 1969 /lib/modules/2.6.32-754.9.1.el6.x86_64/modules.* | grep -i e0a1
[trevor@c6test ~]$
That card is also not supported by the current version of kmod-alx as can be seen from

Code: Select all

$ repoquery --provides kmod-alx
alx-kmod = 0.0-10.el6.elrepo
kabi-modules = 2.6.32-504.el6.x86_64
kmod-alx = 0.0-10.el6.elrepo
kmod-alx(x86-64) = 0.0-10.el6.elrepo
modalias(pci:v00001969d0000109[01]sv*sd*bc*sc*i*)
modalias(pci:v00001969d000010A[01]sv*sd*bc*sc*i*)
modalias(pci:v00001969d0000E091sv*sd*bc*sc*i*)
So 1969:e091 is supported but 1969:e0a1 is not.

You could try asking ELRepo to rebuild the latest kmod-alx to see if that brings in support for that card.

For those who may be interested, I have opened a ticket with the ElRepo folks and they are working on a newer RPM that should move the kmod-alx support up to handle the E2400 and E2500 hardware
