This enables IPv4 over IEEE 1394, providing IP connectivity with
other implementations of RFC 2734 as found on several operating
systems. Multicast support is currently limited.
- NOTE, this driver is not stable yet!
-
To compile this driver as a module, say M here: The module will be
called firewire-net.
