If you wish to use the network interface facilities of the driver,
then you need to attach a network device to each channel that is

you need to follow some additional plumbing rules. They may seem
complex but a look at the example hostess_sv11 driver should
reassure you.

The way most drivers approach this particular problem is to
create a structure holding the Z8530 device definition and
- put that and the syncppp pointer into the private field of

- be put in the private structure conveniently.

Before you register your network device you will also need to
buffer in sk_buff format and queues it for transmission. The
caller must provide the entire packet with the exception of the
bitstuffing and CRC. This is normally done by the caller via
