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 4th column 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.
v1_strm condition column stream 1.
v2_strm condition column stream 2.
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.
