The BF537 ethernet MAC allows for promiscuous mode operation. Refer to PG-8-64
of the BF537 hardware
e_book_o.pdf). Please note that there is no driver support from ADI to make use
of this feature. You can use the ADI provided network stack - lwIP (C:\Program
Files\Analog Devices\VisualDSP 5.0\Blackfin\Examples\ADSP-BF537 EZ-Kit
Lite\LAN) as the starting point to implement this feature.
