There's more to it than that. The notion of a "network" is a rather broad one, including such diverse phenomena as Ethernet, ISDN, TV cable or even roads or TV stations. The notion of a "network device", on the other hand, is a quite specific one, at least in the computer world, and it certainly doesn't include ISDN TAs. In fact, the operation of an ISDN device is much closer to a modem or even an answering machine than to that prototypical network device which is the Ethernet card. This is of course the reason why the Linux kernel puts them in a subsystem of their own. Making them net_device-s just wouldn't work. --=20 Tilman Schmidt E-Mail: tilman@imap.cc Bonn, Germany Diese Nachricht besteht zu 100% aus wiederverwerteten Bits.
