These cards are actually based on Broadcom's 5703 MAC, aka "Tigon III". The Tigon chipset
is really rather cool, in that it includes dual
MIPS cores running at high speed. This enables
all of their "value-added" features, like encryption
assist, firewalling, and TCP segmentation acceleration.
If you can write MIPS assembly, you can run anything that you can fit into 64k on this card.
