1394 Net Adapter Driver |work| Page

To solve this, the driver implements a custom ARP capability:

Unlike Ethernet, where a frame is simply a header and payload, 1394 communication occurs via block write transactions. The driver must encapsulate the IP datagram within a specific data structure known as a GASP (Global Asynchronous Stream Packet) or a block write request to a specific memory address range. 1394 net adapter driver

While older operating systems like Windows XP and 2003 included these drivers by default, modern systems may require manual intervention if the adapter shows a "yellow triangle" or is missing from the Device Manager. To solve this, the driver implements a custom

USB 2.0 (Hi-Speed USB), offering 480 Mbps, effectively killed the consumer adoption of FireWire for general peripherals. While USB did not initially support peer-to-peer networking (USB networking required specialized cables with embedded bridge chips), the ubiquity of USB pushed manufacturers to abandon FireWire ports entirely, reducing the need for the driver.
