In commit 8c213fa "staging: r8712u: Use asynchronous firmware loading",
the command to release the firmware was placed in the wrong routine.
In combination with the bug introduced in commit a5ee652 "staging: r8712u:
Interface-state not fully tracked", the driver attempts to upload firmware
that had already been released. This bug is the source of one of the
problems in https://bugs.archlinux.org/task/27996#comment89833.

In commit a5ee652 "staging: r8712u: Interface-state not fully tracked",
the private boolean "bup" was set false when the interface was brought down,
as that seemed appropriate. This change has not caused any problems when
using NetworkManager or manual control of the device; however, when wicd
control is used, there is a locking problem in wpa_supplicant, as shown in
https://bugzilla.kernel.org/show_bug.cgi?id=42818.
This fix reverts the only code change in commit a5ee652. My
analysis is that "bup" is badly named. In its present form, it
seems to indicate the up/down state of the device, but its usage
is more consistent with an initialized/uninitialized state. That
problem will be addressed in a later patch.
Note: Commit 8c213fa, which introdued asynchronous firmware loading
for this driver, exposed this bug to a greater extent. That bug
is addressed in the next patch in this series.
This bug is also responsible for the bug in
https://bugzilla.kernel.org/show_bug.cgi?id=42815. and this bug is
also part of the problems discussed at https://bugs.archlinux.org/task/27996#comment89950.

This was done to resolve some merge issues with the following files that
had changed in both branches:

I am preparing to convert this driver from semaphore to mutex locking,
The first step has been to eliminate a number of semaphores that were
initialized but never used, and one whose only use was a single "up"
after initialization. A total of 9 semaphores were removed in this process.
One other change was to remove some inline semaphore routines that were
unused.
In addition, several cases had the following structure:
down()
if () {
...
}
up()
The locking overhead was reduced by moving the up/down inside the if
block.

In https://bugs.archlinux.org/task/27996, failure of driver r8712u is
reported, with a timeout during module loading due to synchronous loading
of the firmware. The code now uses request_firmware_nowait().

In r8712_generate_ie(), HT check is no longer done.
Removed r8712_add_ht_addt_info().
Changes to defragmentation handling, and queue selection.
Get TSSI command.
Added an Ad-Hoc check to is_desired_network()
r8712_ind_disconnect() now checks for Linked state.
r8712_xmit_bh() now schedules an xmit tasklet.

padapter->bup is True when the interface has been
brought Up. But it was not being reset when the
interface is taken Down.
This has not caused a known problem, as other
state variables may be compensating for it. Never
the less, it is now properly tracked.

This code is for a completely new version of the Realtek 8192 USB devices
such as the D-Link DWA-130. The Realtek code, which was originally for
Linux, Windows XP and Windows CE, has been stripped of all code not needed
for Linux. In addition, only one additional configuration variable, which
enables AP mode, remains.
