2.5GbE on Supermicro X10SDV 10GbE ports

Has anyone tried this? I couldn't find any information around.

My server runs the SM X10SDV-8C-TLN4F with 2x 10GbE ports via the Intel X557. Intel's product page says nothing about 2.5GbE support, so I'm assuming it's a no-go.

I won't be going 10GbE any time soon on my internal network, but figured I could grab a USB3 2.5GbE for my workstation for a direct connection to the to speed up some file transfers. Thought I'd see if anyone had first hand experience before writing it off.

X557 is a PHY, used to connect to SOC integrated 10G Ethernet MAC
integrated MAC only supports 10G/1G, so there is no 2.5G/5G support

Ah that clears it all up. Completely missed the fact that X557 was PHY not MAC. Thanks much!

Actually, the MAC is listed as multigig. But the PHY is only listed as 1/10
