Commit the first cut of Project Evil, also known as the NDISulator.

Yes, it's what you think it is. Yes, you should run away now.

This is a special compatibility module for allowing Windows NDIS
miniport network drivers to be used with FreeBSD/x86. This provides
_binary_ NDIS compatibility (not source): you can run NDIS driver
code, but you can't build it. There are three main parts:

sys/compat/ndis: the NDIS compat API, which provides binary
compatibility functions for many routines in NDIS.SYS, HAL.dll
and ntoskrnl.exe in Windows (these are the three modules that
most NDIS miniport drivers use). The compat module also contains
a small PE relocator/dynalinker which relocates the Windows .SYS
image and then patches in our native routines.

sys/dev/if_ndis: the if_ndis driver wrapper. This module makes
use of the ndis compat API and can be compiled with a specially
prepared binary image file (ndis_driver_data.h) containing the
Windows .SYS image and registry key information parsed out of the
accompanying .INF file. Once if_ndis.ko is built, it can be loaded
and unloaded just like a native FreeBSD kenrel module.

usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf
into an ndis_driver_data.h file that can be compiled into if_ndis.o.
Contains an .inf file parser graciously provided by Matt Dodd (and
mercilessly hacked upon by me) that strips out device ID info and
registry key info from a .INF file and packages it up with a binary
image array. The ndiscvt(8) utility also does some manipulation of
the segments within the .sys file to make life easier for the kernel
loader. (Doing the manipulation here saves the kernel code from having
to move things around later, which would waste memory.)

ndiscvt is only built for the i386 arch. Only files.i386 has been
updated, and none of this is turned on in GENERIC. It should probably
work on pc98. I have no idea about amd64 or ia64 at this point.

This is still a work in progress. I estimate it's about %85 done, but
I want it under CVS control so I can track subsequent changes. It has
been tested with exactly three drivers: the LinkSys LNE100TX v4 driver
(Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK
(e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It
still needs to have a net80211 stuff added to it. To use it, you would
do something like this:

# cd /sys/modules/ndis
# make; make load
# cd /sys/modules/if_ndis
# ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h
# make; make load
# sysctl -a | grep ndis

All registry keys are mapped to sysctl nodes. Sometimes drivers refer
to registry keys that aren't mentioned in foo.inf. If this happens,
the NDIS API module creates sysctl nodes for these keys on the fly so
you can tweak them.

An example usage of the Broadcom wireless driver would be:

# sysctl hw.ndis0.EnableAutoConnect=1
# sysctl hw.ndis0.SSID="MY_SSID"
# sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc)
# ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up

Things to be done:

- get rid of debug messages
- add in ndis80211 support
- defer transmissions until after a status update with
  NDIS_STATUS_CONNECTED occurs
- Create smarter lookaside list support
- Split off if_ndis_pci.c and if_ndis_pccard.c attachments
- Make sure PCMCIA support works
- Fix ndiscvt to properly parse PCMCIA device IDs from INF files
- write ndisapi.9 man page

.Sh NAME
.Nm ndis
.Nd NDIS miniport driver wrapper
.Sh SYNOPSIS
.Cd "options NDISAPI"
.Cd "device ndis"
.Sh DESCRIPTION
The
.Nm
driver is a wrapper designed to allow binary Windows(r) NDIS miniport
network drivers to be used with
.Fx .
The
.Nm
driver is provided in source code form and must be combined with
the Windows(r) driver supplied with your network adapter. The
.Nm
driver uses the
.Xr ndisapi 9
kernel subsystem to relocate and link the Windows(r) binary so
that it can be used in conjunction with native code. The
.Xr ndisapi 9
subsystem provides an interface between the NDIS API and the
.Fx
networking infrastructure. The Windows(r) driver is essentially
fooled into thinking it's running on Windows(r). 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 .SYS file containing the driver
binary code, and its companion .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
.Pa ndis_driver_data.h
file using the
.Xr ndiscvt 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 9
nodes for each registry key extracted from the .INF file.
.Pp
The
.Nm
driver is designed to support mainly ethernet and wireless
network devices with PCI and PCMCIA bus attachments. (Cardbus
devices are also supported as a subset of PCI.) It there 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.
