Hardware info

On my motherboard (Asus Pro WS X570-ACE) there are two NICs present:
  * Realtek RTL8117
  * Intel I211-AT Gigabit LAN

Leap 15.1 recognizes both, but on a fresh install of Leap 15.2 RC only the
Intel NIC is recognized. That is, the command "ip a" lists only one Ethernet
adapter on 15.2 RC, whereas it lists two on 15.1.

In dmesg I find the following error which I think is relevant:

    [    6.650810] r8169 0000:06:00.1: unknown chip XID 54a

Please add support for the Realtek RTL8117 NIC in the 15.2 kernel.
