Yes you right. Windows also see it as a Marvel evaluation board
but not a network interface. When using Marvell's software on
Windows, then we see that the port is using SMI
(which is the configuration interface).

I'm not able to do that, as we are signed on NDA with them, and I just
don't know what is right and what is wrong.

for it to be soldered to my cpu.
