Did WinOF 4.8 remove "Connected Mode" for ConnectX-2 IPoIB Adapters?

After upgrading to 4.8 my “Mellanox ConnectX-2 IPoIB Adapter” in Win7’s Device Manager no longer has a flag to specify ‘connected mode’ or not… and iPerf testing is showing unconnected-like performance. I was previously running OFED 3.2 and the Advanced tab for the Adapter properties let me toggle the modes.

If this was a workaround for problems with Connected Mode on ConnectX-2’s in Win7… would moving to a ConnectX-3 fix things?

Thanks!
