Calling kthread_run with a single name parameter causes it to be handled

The current value for the maximum receive buffer size is 30720, which is
too large. For long-running systems, memory fragmentation may make it
difficult to obtain the buffers of O(2) needed for aggregation. Buffers
of O(3) are even worse, particularly when not needed. The new size is set
to 9100, which will allow aggregation.

It seems the USB device ID 0bda:8192 is wrongly assigned to the
RTL8192SU chip and not to the RTL8191SU chip in the USB database.
So this patch moves this device ID from the rtl8192u staging
driver to the rtl8712 staging driver.
This patch was tested with a Radicom WIFIHU embedded wireless
module with a RTL8191SU chip and the USB device ID 0bda:8192.
Without the patch the rtl8192u driver claims this device, but
it does not work. With the patch the rtl8712 driver services
this device and it works.

In commit c6dc001 "staging: r8712u: Merging Realtek's latest (v2.6.6).
Various fixes", the returned qual.qual member of the iw_statistics
struct was changed. For strong signals, this change made no difference;
however for medium and weak signals it results in a low signal that
shows considerable fluctuation, When using wicd for a medium-strength
AP, the value reported in the status line is reduced from 100% to 60% by
this bug.

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.
