With the "always-valid" FIFO, the start-of-packet can be used as the request signal, but with the delayed FIFO, you need a request signal that appears at least one cycle before the data. Your options there are to use the "fifo not empty" signal, and to add a register stage that delays the data by one cycle. ...
