AFAICT the SFP+ connectors on the X310 are directly connected to MGTs
on the FPGA. So you could remove one of the ethernet SFP+ connection
from the fpga code, then reuse that SFP+ to directly put a fiber
transceiver and an Aurora core inside.

And that could indeed be a RFNoC block so you can easily direct
traffic to it or to the host. (note that fpga only flow graph are not
supported atm, but should be in the future).
