Unlike USRP1 over USB, it seems specifying the recv_frame_size on "args"
doesn't have any effect on E100.  I see get_max_recv_samps_per_packet()
always returning 506 and I see fragmented segements from recv() calls. Is it
unadjustable for E100 or am I doing something wrong here?

Due to the design of the fpga interface, the largest transfer between the fpga and gpp is 2048 bytes. Beyond this, Josh will need to comment :)
