ieee1394if —
ieee1394if* at fwohci?
The ieee1394if driver consists of two
    layers: the controller and the bus layer. The controller attaches to a
    physical bus (like pci(4)). The
    ieee1394if bus attaches to the controller.
    Additional drivers can be attached to the bus.
Up to 63 devices, including the host itself, can be attached to a
    IEEE1394 bus. The root node is dynamically assigned with a PHY device
    function. Also, the other IEEE1394 bus specific parameters, e.g., node ID,
    cycle master, isochronous resource manager and bus manager, are dynamically
    assigned, after bus reset is initiated. On the
    ieee1394if bus, every device is identified by an EUI
    64 address.
ieee1394if driver first appeared in
  FreeBSD 5.0, as firewire. It
  was added to NetBSD 4.0 under its present name.
ieee1394if driver was written by
  Katsushi Kobayashi and Hidetoshi
  Shimokawa for the FreeBSD project. It was added
  to NetBSD 4.0 by KIYOHARA
  Takashi.
