Feature: Low power mode

[ernestp]

Issue Description

Standby / Low power / Suspend mode

Setup Details

I'm using Ettus B205mini with Android phone. After programming FPGA and starting samples stream power consumption increasing. But when samples stream is stopped power consumption remains on the same level even though hardware not in use.

Expected Behavior

When board is not sampling to reduce power consumption.

Actual Behaviour

Power consumption remains the same as when board is receiving samples.

Steps to reproduce the problem

1. Connect Ettus board
2. Check power consumption
3. Start any GNURadio receive program.
4. Check that power consumption is increased.
5. Close GnuRadio
6. Check that power consumption is not decreased.

Additional Information

Is it possible to reduce power consumption without resetting FPGA program? Using libuhd or with hardware mod?
