Cody Schuffelen c7cdba31ed mac80211-next: rtnetlink wifi simulation device
This device takes over an existing network device and produces a
new one that appears like a wireless connection, returning enough canned
responses to nl80211 to satisfy a standard connection manager. If
necessary, it can also be set up one step removed from an existing
network device, such as through a vlan/80211Q or macvlan connection to
not disrupt the existing network interface.

To use it to wrap a bare ethernet connection:

ip link add link eth0 name wlan0 type virt_wifi

You may have to rename or otherwise hide the eth0 from your connection
manager, as the original network link will become unusuable and only
the wireless wrapper will be functional. This can also be combined with
vlan or macvlan links on top of eth0 to share the network between
distinct links, but that requires support outside the machine for
accepting vlan-tagged packets or packets from multiple MAC addresses.

This is being used for Google's Remote Android Virtual Device project,
which runs Android devices in virtual machines. The standard network
interfaces provided inside the virtual machines are all ethernet.
However, Android is not interested in ethernet devices and would rather
connect to a wireless interface. This patch allows the virtual machine
guest to treat one of its network connections as wireless rather than
ethernet, satisfying Android's network connection requirements.

We believe this is a generally useful driver for simulating wireless
network connections in other environments where a wireless connection is
desired by some userspace process but is not available.

This is distinct from other testing efforts such as mac80211_hwsim by
being a cfg80211 device instead of mac80211 device, allowing straight
pass-through on the data plane instead of forcing packaging of ethernet
data into mac80211 frames.

This section contains all the pre 802.11 and 802.11 wireless
device drivers. For a complete list of drivers and documentation
on them refer to the wireless wiki:

config WIRELESS_WDS
bool "mac80211-based legacy WDS support" if EXPERT
help
This option enables the deprecated WDS support, the newer
mac80211-based 4-addr AP/client support supersedes it with
a much better feature set (HT, VHT, ...)
We plan to remove this option and code, so if you find
that you have to enable it, please let us know on the
linux-wireless@vger.kernel.org mailing list, so we can
help you migrate to 4-addr AP/client (or, if it's really
necessary, give up on our plan of removing it).

---help---
This driver is a developer testing tool that can be used to test
IEEE 802.11 networking stack (mac80211) functionality. This is not
needed for normal wireless LAN usage and is only for testing. See
Documentation/networking/mac80211_hwsim for more information on how
to use this tool.
To compile this driver as a module, choose M here: the module will be
called mac80211_hwsim. If unsure, say N.

This is a driver for wireless RNDIS devices.
These are USB based adapters found in devices such as:
Buffalo WLI-U2-KG125S
U.S. Robotics USR5421
Belkin F5D7051
Linksys WUSB54GSv2
Linksys WUSB54GSC
Asus WL169gE
Eminent EM4045
BT Voyager 1055
Linksys WUSB54GSv1
U.S. Robotics USR5420
BUFFALO WLI-USB-G54
All of these devices are based on Broadcom 4320 chip which is the
only wireless RNDIS chip known to date.
If you choose to build a module, it'll be called rndis_wlan.
