With heavy transmit traffic, once in a while (range 15mins-1hr)
a tx packet was added to a full transmit queue. Under certain
conditions an other packet in the queue gets bumped to make room
for the new packet. This is not considered an error condition, but
normal operation. Despite that, there was an ASSERT(0) that caused
the driver to oops. The ASSERT(0) has been removed. Driver was tested
afterwards.

Both zram and zcache use xvmalloc allocator. If xvmalloc
is compiled separately for both of them, we will get linker
error if they are both selected as "built-in". We can also
get linker error regarding missing xvmalloc symbols if zram
is not built.
So, we now compile xvmalloc separately and export its symbols
which are then used by both of zram and zcache.

Cancel the pending scan operation once the interface is going down to
avoid warnings from the cfg80211 module. Once the interface is down,
cfg80211 checks for any pending scan requests and dumps a warning if it
finds one. It expects the driver to abort any ongoing scan operation
once the driver detects that the interface is going down.

This is an initial staging driver for the GMA500. It's been stripped out
of the PVR drivers and crunched together from various bits of code and
different kernels.
Currently it's unaccelerated but still pretty snappy even compositing with
the frame buffer X server.
Lots of work is needed to rework the ttm and bo interfaces from being
ripped out and then 2D acceleration wants putting back for framebuffer and
somehow eventually via DRM.
There is no support for the parts without open source userspace (video
accelerators, 3D) as per kernel policy.

Firmware design requires a WMI_DISCONNECT_CMD for every WMI_CONNECT_CMD to
clear the firmware previous profile state. There is one case in linux host
driver where two WMI_CONNECT_CMD are given without a WMI_DISCONNECT_CMD.
This causes firmware state to mismatch causing an ASSERT. Use the driver
state variable arConnectPending to track whether a WMI_CONNECT_CMD is
issued to firmware.

A bug was observed during the reconnection phase in the WPA/WPA2-PSK scenario
where the EAPOL frames were going encrypted during an auto reconnection
attempt. The initial 4-way handshake would go fine but then the driver
was getting a command to set default keys sometime later. Setting of an
incorrect flag (TX_USAGE) in the hadrware was causing the EAPOL frames during
the subsequent 4-way handshake attempts to go encrypted causing the AP to
reject the station.
