is the data NIC specific ? if not ... then you mean to say that the data comes over the network ...
-then what i suggest is ... create a listening server(in kernel) get the data and pass it onto your FPGA based board.
- process the data on your board
- put the processed data back with the kernel (on some queue or something) ....
- pass it onto the user space ...
