Filter payloads according to conditions set during run-time.

This function is a wrapper-around the four-condition-column dynamic_filter, just duplicating the columns to feed all its inputs. Thus they share the same configuration bit pattern. All op related to the 2nd to 4th columns should be set to FOP_DC .


W width of all condition column streams, in bits.
WP width of payload column, in bits.
filter_cfg_strm stream of raw config bits for this primitive.
v0_strm condition column stream 0.
pay_in_strm payload input stream.
e_in_strm end flag stream for input table.
pay_out_strm payload output stream.
e_pay_out_strm end flag stream for payload output.
