I'm using RIFFA on Xilinx ML605, part of SoftMC implementation (https://github.com/CMU-SAFARI/SoftMC). I've also installed the RIFFA Linux driver on Ubuntu 14.04.
I'm trying to run option 2 on the testutil application, but calls to fpga_recv always timeout at 25s. If I set the timeout value to 0, the call blocks and never returns. fpga_send seems to work, as it returns the number of bytes sent to the FPGA.
If I run "dmesg | grep riffa", I see no errors. The ML605 is able to register with the driver and negotiate a link rate. But calls to fpga_recv always never return.

Has anyone encountered this before?
