Rob, This did fix my problem and I can now generate deterministic packets!

I am currently using the AXI-stream payload context interface and I am having trouble deterministically generating packets. My current test block outputs the value of the counter as the payload, but the count seems to be about a quarter of the length of the desired length. For instance, my current test block is supposed to output 1024 samples from 0-1022 with a zero as the last payload element. But I am only getting 0-251. This is not an issue that I am having in my functional simulations of the state machine and so I believe that I may be misunderstanding something critical about the interface. Any suggestions are greatly appreciated. I am using UHD 4.0 with an x310 using Dual 10Gig ethernet. A test version of the block with only the transmit packet logic is attached.
