Hi Josh,
The "late" packet gets sent anyway. Right? At least I have verified this at the
receive side. Further, I hope that one L is printed for each "late" burst
(i.e., no. of L's equals no. of late "bursts"). Correct? Finally, how can one
print the metadata to find which of the bursts were late, assuming that there
is a tag containing the burst number?
Thanks,
Yu.

Correct, its a "late" packet. Time in packet > time on the fpga.
