Build open wrt image for gemini platform myditto

Hi guys, I also mean women ;),

I have a myditto NAS with a gemini storlink cs3516 processor. So far so good, I took the NAS 4220b device tree as start and managed to add my device with the new device tree to the menuconfig. I compiled the whole thing and now I compiled it and tried to start the initrams file. It unfortunately stops booting at this line:
gemini-ethernet-port 60008000.ethernet-port eth0: link flow control:
I do not really know what to change now. Is here a crowd still investigating things about this controller type, because I did not find something by known keywords.
