I agree with this solution, I think this is what Ketan's idea was that
I explained terribly in my last email. Hopefully removing the USB
FIFO will allow the extra packet builders room on the chip.

I'm not too concerned about this, although it would certainly improve
the flexibility of the receiver. This might also require redesigning
the usrp_rx mblock, but I'm not confident about that.
