.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
driver needs either
|
||
|
|
.Xr sppp 4
|
||
|
|
or
|
||
|
|
.Xr netgraph 4 .
|
||
|
|
Which one to use is determined by the NETGRAPH_CRONYX option.
|
||
|
|
If this option is present in your kernel configuration file, the
|
||
|
|
.Nm
|
||
|
|
driver will be compiled with
|
||
|
|
.Xr netgraph 4
|
||
|
|
support.
|
||
|
|
Otherwise, it will be compiled with
|
||
|
|
.Xr sppp 4
|
||
|
|
support.
|
||
|
|
.Pp
|
||
|
|
The base I/O port address specified in
|
||
|
|
.Pa /boot/device.hints
|
||
|
|
must match the port address set by the jumpers on the board.
|
||
|
|
The DMA I/O channel and interrupt request numbers are configured
|
||
|
|
by software at adapter initialization.
|
||
|
|
Legal values are:

.Pp
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
driver supports autodetection.
|
||
|
|
As for all non-PNP hardware, using
|
||
|
|
autodetection could lead to some potential problems with other devices during
|
||
|
|
the hardware detection process.
|
||
|
|
It is always better to specify hardware resources manually.
