This reorganizes the device initialization to init page boundaries
before starting the firmware. This matches the flow in the 8192eu
vendor driver.

mac80211 documentation says, the ieee80211_ops.start callback "must turn on
frame reception (for possibly enabled monitor interfaces.)". If not a single
monitor interface does not receive data frames.
Similarly we should not change the data reception based on the association
state.

Monitor mode is enabled by handling the filter flags we get from mac80211 in
rtl8xxxu_configure_filter() and writing them to the RCR register.
By handling the filters, we can also stop setting the BSSID filters in the
association event.

Currently mac80211 does not inform the driver of the session
block ack timeout when starting a rx aggregation session.
Drivers that manage the reorder buffer need to know this
parameter.
Seeing that there are now too many arguments for the
drv_ampdu_action() function, wrap them inside a structure.

There are still four devices which are currently supported both by the new
rtl8xxxu driver and rtlwifi. To not break existing setups enable the support
for these four devices only when CONFIG_RTL8XXXU_UNTESTED is turned on.
Once rtl8xxxu support is found to be good enough the devices can be removed
from rtlwifi and enabled by default in rtl8xxxu.

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)
