[Discuss-gnuradio] Sending without host

[Matthias Schäfer]

 Hi list,
I want to send data direct from the firmware without host. I looked at 
the tx_standalone.c and there came up some questions:

1. Do I have to encapsulate my data into a ethernet packet like it's 
done there or can I simply put something into the buffer pool and set 
the first_line-argument of the dbsm to zero?

2. What's this last_line-Argument for?

3. Does the buffer pool or the DSP delete the data out of the buffer 
after sending?

4. If the ethernet header is necessary, which fpga component interprets 
it? The buffer pool or the DSP?

kind regards,
Matthias
