DEMO Mode with Frame Filter - 7.2 English

The test bench performs the additional task of checking the destination address and source address of the frame using these steps:

1. A fifth frame is pushed into the PHY side receiver interface.
2. The address filter looks at the DA/SA fields of each frame.
3. If there is a mismatch between the DA/SA field of a frame and the 12-byte value the address filter has been pre-programmed with (in the AXI4-Lite state machine), then the frame is dropped.
4. By default, only the fifth frame is dropped because of this mismatch.
