Yeah, I’m seeing issues with this new ethernet expansion card on Fedora 36 as well. Seems to work in Windows, though, so maybe the r8152 driver has some problems?

This Ethernet Expansion Cards do seem to be very delicate.
I can truly confirm that all my Ethernet switches within my lab environments are not the issue as I have many desktops, laptops, Dongles, MacBook Pros, Mac Minis, Servers, and docking stations working without any issue.
I am getting greater success to always do a reboot after I insert the Expansion Card to a new slot – I try to the rear USB C ports (right now as I am writing this post the card is on the left side back port).
I am seeing the card go offline and online periodically. I don’t have that experience with any other Ethernet device.
I have swapped the two cards between my original Frame work laptop (11th Generation I received in DEC 2021) and the new 12th Gen I received in September 2022. The experience is the same.
I am using POP!_OS 22.04 using kernel 5.19.0-76051900 on both systems.
No matter the configuration of the card or laptop the experience is the same where I see periodic drop and start of the network adapter.
On both laptops the Ethernet Expansion Card is recognized as USB Ethernet device (image attached from the Framework 11-gen as both cards do not work as well as the other laptop).
The PCI Ethernet device is my Sonnet SOLO10G SFP+ device – a network for a TrueNas server.
I am not sure if I am going to return 1 or both.
I’m running Ubuntu with kernel 5.19.0, only changes were adding the realtek UDEV rules.
Inserting the card is like roulette, sometimes it just doesn’t work:

Once it works, I’m getting good performance with iperf3 as client:

I’ve tested this against multiple machines each on a 10G link, which all achieve 9.39Gb/s between one another.
Also, once I disconnect the ethernet cable and reconnect, it will never link again until I reset the card.
Update: Once the card is working hard after about 5 minutes, it will disconnect, this seems to repeat over and over. I think framework made a dud. I’d advise people not order this until these problems are fixed, I think I’m going to try to return mine.
