This module is used to generate user traffic to each of the AXI4-Stream data, UFC, NFC, and USER-K interfaces. The module contains
pseudo-random data generated using a linear feedback shift register (LFSR) with a known
seed value. The FRAME_CHECK module can use the same configuration to check the data
integrity of the aurora channel. The inputs for this module are user_clk, reset, and channel_up. The FRAME_GEN module follows the AXI4-Stream protocol and transmits the user traffic.
