Broadcast Frame. When set, this bit indicates that the received frame has a Broadcast address.
RX Packet Format
The RX status words can be read from the RX status FIFO port, while the RX data packets can be
read from the RX data FIFO. RX data packets are formatted in a specific manner before the host can
read them as shown in
status word from the RX status FIFO, to ascertain the data size and any error conditions.
