Realtek 10 GbE USB Adapters might be on the way?

[Tinkerer]

Oke so we do see a little issue here that wasn't obvious before. On the upside it didn't crash .

But we do see this:

• TX (9900K → 12900K): consistent ~9.83 Gbits/sec
• RX (12900K → 9900K): average ~5.55 Gbits/sec.

This begs the question: which side had the Diewu and where was the Lueko?
I wonder what would happen if you run the same iperf command from the other PC without changing anythging else.

If you're willing, please could you also test P2P, no switch in between? Modern nics support auto-MDIX and detect P2P and automatically switch so no crosslink cable required. Reqular UTP will do just fine.

PS. I have the USB and Diewu on order from Ali. I expect it next week or so.

Thanks for your tests! Appreciate you're taking the time.

the Diewu is in the 12900K
i dont run flow control one side always seems to take a hit due to buffers being full
so having to wait to send more

this just seems to be what happens when both directions are being saturated

I dont run UTP i have a bit of STP on 2.5Gbps links but 10Gbps is mid migration to SFP+ Optics and Dacs
e.g. all PC's are SFP+ not RJ45

I have just Tested some RTL8127's in a ASM2464 USB4/TB4 Controller
with the goal of making my own SFP+ card

The cable just arrived

All is looking good sofar and its being powered by the 3.3v rail so 12v isnt required
I will test all cards i have and edit this post

DIEWU RTL8127 PCIe 4.0x1 RJ45 = Working (9.91Gbps Payload 9K Frames)
LEKUO RTL8127 PCIe 4.0x1 RJ45 = Working (9.91Gbps Payload 9K Frames)
DIEWU RTL8217AT PCIe 3.0x2 RJ45 = Working (9.91Gbps Payload 9K Frames)
DIEWU RTL8127ATF PCIe 3.0x2 SFP+ = Working (9.91Gbps Payload 9K Frames)
LEKUO RTL8127ATF PCIe 3.0X2 SFP+ = Will be tested when one arrives i dont expect problems (my 2 in use are hard to get get at)

DIEWU RTL8127AT RJ45 PCIe 3.0 x2




LEKUO RTL8127 RJ45 PCIe 4.0x1



DIEWU RTL8127ATF SFP+ PCIe 3.0x2 50CM DAC

Temp Setup until the LEKUO 8127ATF arrives

There is nothing stopping someone releasing a retail USB4/Thunderbolt4 RTL8127ATF

DIEWU RTL8127ATF SFP+ 50CM DAC

Odroid also made a neat detachable M.2 RJ45 nic on rtl8127, 2 lanes of PCIe 3.0: https://wiki.odroid.com/accessory/connectivity/m.2_to_10gbe_adapter

Given that they published a schematics, I wonder if it would be possible to remake with for SFP+ cage

I've been checking every few weeks and this turned up in my search today, M.2 to 10G SFP+ Adapter RTL8127ATF 10GbE.

In Germany it says not available (redirects to de.aliexpress.com). Need to check with VPN. What's the price on this bad boy?

ok, we might finally be getting real drivers for the realtek in 7.2:

Linux 7.2 To Support Realtek RTL8159 10GbE USB Ethernet - Phoronix

It looks like the PCIe 4.0 x1 SFP+ variant is also available now on Aliexpress.

At last, a use for all those pcie 4.0 x1 slots on my motherboard. Shame it's Realtek.

Finally!

The fact that nobody made versions like these before almost made me think that the RTL8127ATF simply didn't support PCI-E 4.0 for some reason.

Had more problems with Broadcoms, Mellanox and Intels in the last years than with realtek. Relly, a 8139 can destroy a reputation for decades. At least Suspend works under Linux with them. And the 2.5GB were never as buggy as the v225s
