Ettus B210 has a maximum sampling rate of 61.44MSPS. Exceeding this limit results in unexpected behavior. Prevent this from occurring by decreasing the maximum sample rate by from 61.444MSP to 61.44MSP (-4k).
Add LO offset support.
Only set tx/rx_bandwidth after getting tx stream, to reduce TX LO leakage for <10MHz bandwidths.
Check for reference and LO lock before getting streams.
Set bit size to be 16 for interpolators and decimators.
Match buffer size to UHD.
Don't destroy TX stream, as there appears to be a bug when recreating it.
Catch exception when checking for TX underflow.
Increase RX FIFO size, to reduce overflows at high sample rates.
Allow RX to continue streaming after receiving timeout.
