Jon Szymaniak 748ac00b25 bladerf: Use rational sample rate functions
libbladeRF provides accessors for rational sample rates, which the
integer sample rate functions use under the hood. Therefore, there's no
need to check if the requested rate contains a fractional portion and
switch between the two sets of functions.

Dimitri Stolnikov 9c6ac9e3e3 rfspace: add support for RFSPACE SDR-IQ and SDR-IP
Usage example:

osmocom_fft -a sdr-iq=/dev/ttyUSB0
osmocom_fft -a sdr-ip=host[:port]
osmocom_fft -a netsdr=host[:port][,nchan=2]

The following named gain stages are available:

SDR-IQ: ATT: -20 to +10 dB, in 10dB steps
SDR-IP: ATT: -30 to 0 dB, in 10dB steps

The ftdi_sio driver is being used for SDR-IQ. It creates a character
device of the form:

crw-rw---- 1 root dialout 188, 0 Dec 19 22:14 /dev/ttyUSB0

To be able to open the device without root permissions add yourself to
the "dialout" group or do a "chmod 666 /dev/ttyUSB0" after pluggin in.

Jon Szymaniak 44bd325a86 bladerf: Moved initializations to bladerf_common.c, misc. cleanup
Common parameter handling has been moved into bladerf_common::init().

The buflen parameter is now in units of samples, not bytes. This
deviates from the other gr-osmosdr items. However, with the requirement
that buffers be in multiples of 1024 samples, this makes specifying this
parameter a bit easier. The user shouldn't need to know we're operating
on SC16Q12 values under the hood, and have to calculate accordingly.

To avoid confusion when both a bladeRF source and sink are in a flow
graph a [bladeRF source/sink] prefix has been added to output. Error
number have been replaced with bladeRF string representations of these
error values.

Firmware flashing has been removed. The bladeRF-cli or bladeRF-flash
tools are the preferred route for firmware upgrades.

Jon Szymaniak 03c42ef320 bladerf: Moved no longer "common" items out of bladerf_common
The gr_complex FIFO is no longer used on the TX side, so it doesn't
really make sense to have it in bladerf_common. The associated items
have been moved into bladerf_source, and some renaming has been done in
bladerf_sink to tidy up.

Pending further performance tests of the bladerf_source, the _fifo
member (boost::circular_buffer) may need to be replaced.

Dimitri Stolnikov 8facbbcca1 netsdr: add support for RFSPACE NetSDR receiver
- implements broadcast UDP based device discovery
- prints device information (serial/versions) on startup
- reads available frequency range(s) from the device
- integrity checks of IQ stream using sequence numbers
- automatic bandpass or a wideband lowpass selectable

The following named gain stages are available:

ATT: -30 to 0 dB, in 10dB steps

Known limitations:

- setting the sample rate is possible only before the
  flowgraph has been started

Dimitri Stolnikov a71fbeeaa5 hackrf: implement device discovery
Unfortunately libhackrf still doesn't offer a way to enumerate devices
*or* to open a specific device by index or it's serial number. Thus we
have implemented a rather hack-ish way to detect the presence of a
device by trying to open it and closing right after that.

Jon Szymaniak 9b41c6aa20 bladeRF: Refactored buffering scheme in sink
Removed the use of an intermediate sample FIFO in the sink
implementation. Note the the FIFO has not been moved out of
bladerf_common --> bladerf_source_c in this commit.

work() now handles converting samples from complex to SC16_Q12, and filling
"transmit-ready" buffers. The callbacks are now only responsible for
marking the provided buffer free, and returning the next buffer.

It appears that a small deadlock issues remains in this changest, which
can be induced by:
 1: Using a small sample rate (160Khz)
 2: Switching back and forth between sinusoid <-> GSM burst

 In this case, it appears that work() is blocked waiting for a buffer to
 become free. More investigation here is required...
