Ah, I see, you changed the flow graph. Your problem might be that the 
transmitter outputs a tagged stream and, therefore, requires the Packet Pad 2 
block as in the original flow graph. You replaced it with a block that expects 
a normal stream input that contains frames that are already marked with 
“tx_sob” and “tx_eob” tags. I would recommend to keep the original 
configuration.
