3dfb8e844f wifi: rtl8xxxu: Support new chip RTL8188EU
This chip is found in cheap USB devices from TP-Link, D-Link, etc.

Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps.

Chip versions older than "I cut" need software rate control. That will
be in the next commit. Until then MCS7 is used for all data frames.

The "I cut" chips are not supported. They require different firmware
and initialisation tables. Support can be added if someone has the
hardware to test it.

c888183b21 wifi: rtl8xxxu: Support new chip RTL8188FU
This chip is found in the cheapest USB adapters, e.g. 1.17 USD with
VAT and shipping from China included.

It's a gen 2 chip, similar to the RTL8723BU, but without Bluetooth.
Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps.

The vendor driver rtl8188fu version 4.3.23.6_20964.20170110 [0]
was used as reference. The CD shipped with the device includes a
newer driver, version 5.11.5-1-g12f7cde4b.20201102, but that one
couldn't complete the WPA2 key exchange thing for whatever reason.

181725dd4f rtl8xxxu: move rtl8188[cr] and rtl8192c related code into rtl8xxxu_8192c.c
This moves the code for rtl8188c, rtl8188r, and rtl8192c into it's own
file. This is purely a code moving exercise, there is no change to the
code itself.

20e3b2e97e rtl8xxxu: move rtl8723a related code into rtl8xxxu_8723a.c
This moves the rtl8723a code into it's own file. This is purely a code
moving exercise, no code changes.

This device specific file is a lot smaller since the gen1 chips
(8723a, 8188c, 8188r, 8192c) share a lot more common code than the
gen2 chips.

This moves the rtl8723b code into it's own file. This is purely a code
moving exercise, no functional changes. This did expose
rtl723a_h2c_cmd() as a function that should be refactored into a gen1
and a gen2 version.

26f1fad29a New driver: rtl8xxxu (mac80211)
This is an alternate driver for a number of Realtek WiFi USB devices,
including RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU.
It was written from scratch utilizing the Linux mac80211 stack.

After spending months cleaning up the vendor provided rtl8723au
driver, which comes with it's own 802.11 stack included, I decided to
rewrite this driver from the bottom up.

Many thanks to Johannes Berg for 802.11 insights and help and Larry
Finger for help with the vendor driver.

The full git log for the development of this driver can be found here:
git git://git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git
    branch rtl8723au-mac80211

This driver is still under development, but has proven to be very
stable for me. It currently supports station mode only. It has support
for OFDM and CCK rates. It does lack certain features found in the
staging driver, such as power management, AMPDU, and 40MHz channel
support. In addition it does not support AD-HOC, AP, and monitor mode
support at this point.

The driver is known to work with the following devices:
Lenovo Yoga (rtl8723au)
TP-Link TL-WN823N (rtl8192cu)
Etekcity 6R (rtl8188cu)
Daffodil LAN03 (rtl8188cu)
Alfa AWUS036NHR (rtl8188ru)
