Ethernet link speed auto detection

Hi I have a custom board with a ethernet PHY connected to the FPGA using RGMII. I am using triple speed ethernet and iniche. I do not have the signals set_10 and set_1000 from the PHY. I can...

I am able to read the PHY registers over MDIO (MDIO Space 1 in the TSE component). I see that the correct speed is reported but it is not reflected in the ETH_SPEED bit in the command_config register. I am using a tcp/ip stack (iniche) and it is working. The project is based on the simple socket server RGMII template. I have added the PHY profile with alt_tse_phy_add_profile so iniche should have information of where to find the correct status register and bit location for the link speed. Is there something else I am missing to get it to detect and change the speed?
