MIMO with USRP2 and Raw Ethernet driver

Hi,

I would like to implement a 2x2 MIMO receiver using the MIMO expansion
cable. I don’t have the UHD drivers installed but the Raw Ethernet ones.

Is it possible/easy to do this using the RAW Ethernet drivers or is it
easier to just install UHD?

If I need to install the UHD do I need to re-install all of GNU radio?

Thanks in advance,
Pedro
