Re: [Discuss-gnuradio] How to transmit synchronously with timestamp using VRT code.

[Josh Blum]

If your packets are too large, there is some fragmentation logic that 
also plays with the burst flags. You may be seeing this fragmentation 
within the usrp2 driver at work. Look inside the usrp2_impl.cc in the 
tx_raw method.
