[Orange Pi 3] [Regression] GMAC hardware offload broken in kernel 6.12.58

[GBH]

Hello Respected Supporters,

 

After upgrading to Armbian 26 (kernel version 6.12.58), the onboard network card (end0) experienced a severe degradation in transmission performance (reduced to approximately 1/10 of previous levels). Upon investigation, it was discovered that the kernel driver (dwmac-sun8i) has locked all hardware offload features (TSO/GSO/Checksum), forcing the CPU to handle all processing in software.

root@orangepi3:~# uname -r
6.12.58-current-sunxi64

root@orangepi3:~# dpkg --list | grep linux-image
ii  linux-image-current-sunxi64       26.2.0-trunk.48                         arm64        Armbian Linux current kernel image 6.12.58-current-sunxi64

Hello and thank you for the problem report.

 

What solution did orangepi.org provide for you?

 

As you can see, nobody in the Armbian community was interested to step up and support this board and from what I have heard through the grapevine this is because of the poor support that orangepi.org gives to FOSS projects and communities such as armbian.com. 

 

Armbian has already pushed another update for Sunxi64.  Maybe you are in luck and the problem is already fixed.  If not, we are happy to accept a PR once orangepi.org has published a solution.
