Last few packets dropped

Hi all

When I ran benchmark_ofdm_tx.py, I noticed that the last few packets
(5-20, depends on the packet size and modulation) always got dropped.
The spectrum analyzer shows nothing transmitted. Using --discontinuous
helps to reduce the # of dropped packets, but the 2-3 packets of the
last run still got last.

Similar case when I run tunnel.py under the example ofdm folder. When
I ping another machine, spectrum analyzer shows no transmission at all
although the laptop screen shows “Tx: len(payload)=42”.

I searched the mailing list and found similar discussion two years ago
about the dropped packets problem but no solusion there. Has anybody
successfully got tunnel.py working?

My OS is Ubuntu 7.04 and I checked the gnuradio several days ago. I
use USRP1 and RFX2400. Thanks!

Best regards,
