The support code handles most common card configurations and
supports running both Cisco HDLC and Synchronous PPP. With extra
glue the frame relay and X.25 protocols can also be used with this
driver.

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
present and in use. In addition to use the SyncPPP and Cisco HDLC
present and in use. In addition to use the generic HDLC
you need to follow some additional plumbing rules. They may seem
complex but a look at the example hostess_sv11 driver should
reassure you.

<para>
The network device used for each channel should be pointed to by
the netdevice field of each channel. The dev-&gt; priv field of the
the netdevice field of each channel. The hdlc-&gt; priv field of the
network device points to your private data - you will need to be
able to find your ppp device from this. In addition to use the
sync ppp layer the private data must start with a void * pointer
to the syncppp structures.

</para>
<para>
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
the network device. The network device fields of the channels
then point back to the network devices. The ppp_device can also
be put in the private structure conveniently.

If you wish to use the synchronous ppp then you need to attach
the syncppp layer to the network device. You should do this before
you register the network device. The
<function>sppp_attach</function> requires that the first void *
pointer in your private data is pointing to an empty struct
ppp_device. The function fills in the initial data for the
ppp/hdlc layer.
If you wish to use the generic HDLC then you need to register
