-Removing the wait signal from the pipeline
-Assumption is that the prog_full is used on fifo, allowing two entries
to be captured in fifo.
-May revisit this at some time...
-When a read response is detected, there should be no spurious transactions to the RD/WR request fifos.
-Move the "filter" backt to the erx_protocol block
-Removed the remap bypass signal (was hacky)
-Passes simulations again..
