           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.
