Furthermore, when reporting an unsupported device, please provide info from lspci -nn.
For example:
$ lspci -nn | grep -i net
00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (14) I219-LM [8086:15f9] (rev 11)
The important detail is the device ID, which is [8086:15f9] in the sample above.
If you can find the ID from ELRepo | DeviceIDs then you know whether and which kmod package ELRepo has for that device.
