[PATCH] gr-osmosdr blocks for the Red Pitaya SDR transceiver

Hello Dimitri, I've put together two simple gr-osmosdr blocks for the Red Pitaya SDR transceiver. They are based on the file block with some pieces borrowed from the rtl_tcp block. Would it be possible to add these blocks to the gr-osmosdr code repository? The patch is in the attachment. Some information about the Red Pitaya SDR transceiver can be found at: http://pavel-demin.github.io/red-pitaya-notes/sdr-transceiver Best regards, Pavel
