Why not use the 1GbE port on the ROACH2? No need to go for 10GbE (SFP+)

As I explained in a previous email, I am looking for a way to send the
slow-throughput ROACH2 data (~25 Mbps) to a PC without using the SPF+
ports on the PC side. Mobility is important for the project that I am
working, so I want to be able to use any laptop for that purpose
without the burden of having to have a 10 GeB SPF+ card
I first considered the 1 GbE but this implies a big reconfiguration of
the design sine the outputs are 8 bit instead of 64 that the 10 GbE
Have anyone tried to use a SPF+ to 1 GbE RJ45 connector like the ones
in the attached picture?
I did some research and I found that the Quad SFP+ Mezzanine board
uses the Vitesse VSC8488XJU chip which in theory should allow such
connection, as you can see in this spec. sheet
So far, I tested 2 different adapters at port 0 with no luck.
Does anyone know if this is possible?
Is the 1 GbE option enable in the mezzanine board?
