[Testers-Needed] Converting Any Realtek Ethernet to Intel Killer Ethernet chip

[THEBOSS619]

Any luck getting the RTL8156 usb chipset to accept the Killer drivers?

I have the "Realtek Gaming USB 2.5GbE Family Controller" variant with the following HWIDs:
USB\VID_0BDA&PID_8156&REV_3104
USB\VID_0BDA&PID_8156

Will try to do it and look into it as soon as I get free time for it will get back to you with new driver if needed

Been following up till now and I'm curious if anyone has had any success with:
Realtek PCIe 5GbE: 8126 chipset

PCI\VEN_10EC&DEV_8126&SUBSYS_012310EC&REV_01
PCI\VEN_10EC&DEV_8126&SUBSYS_012310EC
PCI\VEN_10EC&DEV_8126&CC_020000
PCI\VEN_10EC&DEV_8126&CC_0200

No rush, thank you.

Realtek driver I'm using is 10.73 (standard w/ power saving). Oddly, they keep changing the date stamp on the driver and its file size has grown but the version # has stayed the same. ( there were older ones, 10.71 and 10.72, which seemed a little off, like they are still developing the driver or patching for security? )

Definitely no rush...it'll be interesting to see if the Killer drivers make this chip perform any better.

STILL NO RUSH

Just want to document another DATE STAMP change with same version number:
I don't understand what's happening on their end (Realtek)?

I can try

PCI\VEN_10EC&DEV_8125&SUBSYS_23141565&REV_05
PCI\VEN_10EC&DEV_8125&SUBSYS_23141565
PCI\VEN_10EC&DEV_8125&CC_020000
PCI\VEN_10EC&DEV_8125&CC_0200

I'm using your wifi drivers and they work like a charm.

Will add it to my to-do list regarding ethernet driver development unfortunately it is still on pause until further notice, the place I am currently in doesn't provide any kind of ethernet access so I can't develop further blindly without testing it.

I'm really sorry for late reply, for unknown reasons , I didn't receive any kind of notification of your post, times stamp changes doesn't mean that they made changes on drivers, as long as .sys file is not touched and have the same versioning numbers then it will always be the same

I hear what you are saying but the file size should remain the same as well. If you look at post# 81 you see it varies when it should not. This tells me something is off, one significantly.

I'm interested for an explanation if you have the time, thanks.

Indeed Indeed, file size should be the same as well. Do you have those files? If possible Can you send it to me? I'm gonna look into it as soon as I get the time

((You would have to PM me on how to send files.)) Might be moot with the new 10.74 release, let me know.

hi, since the topic is experimentation on modded Realtek Ethernet drivers im posting this here.

One big issue on these devices is how PCIe caps / link are set: Max Read requests=512; MaxPayloadSize=128; link 2.5GT/s which uses 8/10 encoding wasting 20% overhead;
The maximum payload size (MPS) is set on all devices based on smallest maximum on any device in the chain of that ROOT PCIe complex. Severe limiting bus efficiency;
Another tweak ideia would be set gen3 8GT/s so 128/130 encoding could be used.

I checked PCIe root bus with detail view of HWInfo. every root complex in my B550 mobo with Cezanne cpu could use 512 bytes but onboard Realtek GbE limits chipset tree to 128, so my USB, SATA suffer.
I did some tests disabling onboard ethernet, and using smarphone Tether; Chipset tree raized to 512bytes payload and everything "felt" more responsive!
Now i m trying to find a tool to experiment in win11 or force PCIe regs in a tweak BIOS menu like "Universal AMD Form Browser"

Wow, that's a great find! and amazing troubleshooting experiments , I will look & search into that and see if there's something can be made on driver side that can manipulate the PayloadSize but regarding the PCIe limiting it to Gen3 I guess that's totally under BIOS control.

Thank you for your time and sharing this info.!

Welp time to uefi mode again to unlock these settings to play around with (I'm stuck with basic MSI bios lol)
I have an integrated 2.5 gaming Lan on my mobo. It's not the best so I decided to buy a pcie lan card ONLY FOR IT TO TURN OUT TO USE THE SAME RTL 8125 ‍‍‍‍the best performance I've gotten is RSS with 1 queue, 1 interupt limit and locked to core 0. Any other core adds latency (idk why) and im limited to ndis driver for RSS. Does this killer driver enable RSS to work with netadaptercx driver?
