Ethernet on Rock64

Wolfgang
Hello everyone! I’ve been trying to install OpenBSD on my Rock64 SBC, but unfortunately i ran into some problems with the onboard Ethernet adapter. I wasn’t able to install the sets using http, so i started looking into it and when i tried to ping the router, i noticed that almost half of the packets gets lost on the way. I contacted the author of this guide https://github.com/krjdev/rock64_openbsd for some help, and he told me that the culprit might be the TX/RX values of the adapter. So he sent me a dtb file with the right values, unfortunately after putting it into the "rockchip” directory on sd0i there was no change to the adapter’s behaviour. It seems that the driver doesn’t respect the Tx/Rx values set in the device tree file. Unfortunately, i don’t know much about OpenBSD and its driver system, so i haven’t been able to find a way to solve that problem.
What can be done here?
