Mikrotik RB2011-UiAS-IN SFP. Is it working?

Hello. OpenWrt has been successfully installed on this device. But when I tried to set-up it's SFP, it seems it fails to work. When ISP wire is connected with SFP-module which inserted in appropriate router's port, Network -> Switch shows SFP port is empty. I tried to assign a network configuration to SFP interface but after it I can't even ping at least ISP gateway. So can anyone confirm the successful SFP-port configuration on its device? Because I was fail to and set up it by inserting SFP-module into Media-converter and connecting it to Mikrotik's WAN port.
Thanks.

Hello, I have the same problem as you but I haven't been able to find help, there is a i2c patch but I don't know how to apply it and where. I didn't get any help. You need to modify the code 0x0230c300 somewhere in the march_*.c file but I can't find it on my router
