OK, so how do I get post-ADC rssi out of the USRP for any arbitrary

My radio astronomy receiver could benefit from this, especially if the
RSSI is low-pass
  filtered to some degree onboard the FPGA.   Part of my host side stuff
  RSSI from the samples coming from the USRP (by squaring and low-pass

I could probably save about 20% of my CPU load if I could get that
squaring, and at least
  a first-stage low-pass filter done on the FPGA.
