|
.Nd NDIS miniport driver wrapper
|
|
.Sh SYNOPSIS
|
|
.Cd "options NDISAPI"
|
|
.Cd "device ndis"
|
|
.Cd "device wlan"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver is a wrapper designed to allow binary
|
|
.Tn Windows\[rg]
|
|
NDIS miniport
|
|
network drivers to be used with
|
|
.Fx .
|
|
The
|
|
.Nm
|
|
driver is provided in source code form and must be combined with
|
|
the
|
|
.Tn Windows\[rg]
|
|
driver supplied with your network adapter.
|
|
The
|
|
.Nm
|
|
driver uses the
|
|
.Nm ndisapi
|
|
kernel subsystem to relocate and link the
|
|
.Tn Windows\[rg]
|
|
binary so
|
|
that it can be used in conjunction with native code.
|
|
The
|
|
.Nm ndisapi
|
|
subsystem provides an interface between the NDIS API and the
|
|
.Fx
|
|
networking infrastructure.
|
|
The
|
|
.Tn Windows\[rg]
|
|
driver is essentially
|
|
fooled into thinking it is running on
|
|
.Tn Windows\[rg] .
|
|
Note that this
|
|
means the
|
|
.Nm
|
|
driver is only useful on x86 machines.
|
|
.Pp
|
|
To build a functional driver, the user must have a copy of the
|
|
driver distribution media for his or her card.
|
|
From this distribution,
|
|
the user must extract two files: the
|
|
.Pa .SYS
|
|
file containing the driver
|
|
binary code, and its companion
|
|
.Pa .INF
|
|
file, which contains the
|
|
definitions for driver-specific registry keys and other installation
|
|
data such as device identifiers.
|
|
These two files can be converted
|
|
into a kernel module file using the
|
|
.Xr ndisgen 8
|
|
utility.
|
|
This file contains a binary image of the driver plus
|
|
registry key data.
|
|
When the
|
|
.Nm
|
|
driver loads, it will create
|
|
.Xr sysctl 3
|
|
nodes for each registry key extracted from the
|
|
.Pa .INF
|
|
file.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver is designed to support mainly Ethernet and wireless
|
|
network devices with PCI, PCMCIA and USB bus attachments.
|
|
(Cardbus
|
|
devices are also supported as a subset of PCI.)
|
|
It can
|
|
support many different media types and speeds.
|
|
One limitation
|
|
however, is that there is no consistent way to learn if an
|
|
Ethernet device is operating in full or half duplex mode.
|
|
The NDIS API allows for a generic means for determining link
|
|
state and speed, but not the duplex setting.
|
|
There may be
|
|
driver-specific registry keys to control the media setting
|
|
which can be configured via the
|
|
.Xr sysctl 8
|
|
command.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "ndis%d: watchdog timeout"
|
|
A packet was queued for transmission and a transmit command was
|
|
issued, however the device failed to acknowledge the transmission
|
|
before a timeout expired.
