​Hi,

If this is using external PHY (consist PCS and PMA), and the FPGA is only consist MAC, then I would suggest you to double check with the external PHY datasheet, and see if there is any setting required. I suspect the auto-negotiation is not success, and this is why i suggest to disable it, and see if it works.

If you set PROMIS_EN = 0, and yes, it should filtering if the destination address does not match. What is the resisters mac_0 ,mac_1, and supplementary address that you configure? And what address that you receive but not filter? Did you try to do a software reset (SW_RESET)?
