Bug#1143994: general: Ethernet driver r8169 is used for RTL8125 chipset by default and disconnects intermittently

Package: general
Severity: important
X-Debbugs-Cc: [email protected]

Dear Maintainer,

I am using Debian Testing on my desktop PC, which uses a Realtek ethernet chipset. 
My internet connection would regularly disconnect (usually for a minute or less, sometimes it stayed disconnected until I restarted my computer). 

I ran the following command and found the output said I was using a mis-matched kernel driver for my ethernet chip:

lspci -k | grep -A3 Ethernet
06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
        Subsystem: Micro-Star International Co., Ltd. [MSI] Device 7d45
        Kernel driver in use: r8169
        Kernel modules: r8169

r8169 I assume is used to cover a number of chipsets. But mine was 8125, and it did not like it. 

I switched ethernet drivers using this package:
r8125-dkms/testing,testing,now 9.016.01-1 all [installed]

After installing that package I no longer had issues with my ethernet. I believe this chipset should be set to use the 8125 driver by default, to prevent this.

An additional note about my troubleshooting that may not be relevant: I did some wrong troubleshooting steps before installing that package (thanks AI) so I ended up blacklisting my previous driver r8169, to prevent it from loading in first. That was before I discovered that debian had a package with the driver conveniently available. I may still have that blacklist enabled, preventing 8169 from loading.


Thank you for your attention.
I'm sorry if I sent this to the wrong place, I wasn't sure what "package" my default kernel ethernet driuver would be.
