[Discuss-gnuradio] USRP2, is that possible to skip the Ethernet and pass data through general purpose (physically accessible) inputs to the FPGA?

Hi,

I am using USRP2+RFX2400 board and trying to adapt our packetized 
communication on the board. As I understand the Ethernet does its own 
packetization on information data and we don't like that. therefore we 
are looking into avoid passing our information data to the board through 
Ethernet. We are also fine to make the configuration values for other 
peripherals on the board (such as DAC, ADC and daughter boards) fixed so 
that we still can get away with no Ethernet interface.  so we are 
interested to know if there is a general purpose input bus (at least 5 
pins) that I can use to pass my data serially to the FPGA. That means I 
would like to see if it is possible to remove all the Verilog codes in 
FPGA related to handling the Ethernet interface and get the data I'd 
like to process through a general purpose input bus (at least 5 pins for 
clock and serial data input and 3 handshaking signals) instead of 
Ethernet port. For that reason, I need this general purpose bus to be 
physically accessible on the board so that I can connect them to a 
digital signal generator. Do you have any suggestion/recommendation for me?

Thanks,
Malihe
