staging: wlan-ng: remove undefined function

The function p80211wext_get_wireless_stats() is declared in the code
but has neither been defined nor referenced.

It's definition was removed 13 years ago in the
commit cb3126e60ffc ("Staging: wlan-ng: Switch from wext to cfg80211")

drivers: staging: wlan-ng: Remove GPL/MPL boilerplate

Remove the license boilerplate as there is already SPDX license
identifier added in b24413180f5600 ("License cleanup: add SPDX GPL-2.0
license identifier to files with no license") which fulfills the same
intention as the boilerplate.

staging: wlan-ng: Remove pointless a3/a4 union

There is no need for the a3/a4 union. The two structs are identical
except for the addition of a4. Excepting one place, the structs are
only ever used in the union, and the union is always allocated at full
size. The one instance of the a3-specific struct can be replaced with
the full version, as no sizing information is used. Replace the union
with the a4 version of the struct. "diffoscope" reports there are no
object code differences after this change.

staging: wlan-ng: add SPDX identifiers to all wlan-ng driver files

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the wlan-ng driver files with the correct SPDX license identifier
based on the license text in the file itself. The SPDX identifier is a
legally binding shorthand, which can be used instead of the full boiler
plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

Staging: wlan-ng: Switch from wext to cfg80211

Switch driver over from wext to cfg80211 interface.

Some Notes:

- This patch moves the driver wholesale from wext to cfg80211. Wext
support is still provided through the cfg80211 provided wext
compatability layer.

- Currently only infrastructure mode is implemented. Ad hoc mode is not
yet implemented, but can be added.

- It does not support connecting to a specified bssid, instead roaming
is handled by the card itself. This matches the behaviour of the
existing driver.

- It has been tested using NetworkManager (via wpa_supplicant)
configured to use the wext compatability layer, and then again with the
native nl80211 layer.

Staging: add wlan-ng prism2 usb driver

This adds the wlan-ng prism2 USB driver to the drivers/staging tree.

The code was originally written by the linux-wlan-ng team, patched by
some Novell engineers to properly work on newer kernels, and then hacked
into place in order to get it to build properly in a single subdirectory
within the kernel tree by me.

It supports a wide range of older USB prism2 devices, and contains a
80211 stack to support this single driver.
