Rate control algorithms are supposed to stop processing when they
encounter a rate with the index -1. Checking for rate->count not being
zero is not enough.
Allowing a rate with negative index leads to memory corruption in
ath_debug_stat_rc().
One consequence of the bug is discussed at

Driver maintains different flags for WEP, WPA, WPA2 security modes.
Appropriate flag is set using security information provided in
connect request. mwifiex_is_network_compatible() routine uses them
to check if driver's setting is compatible with AP. Association is
aborted if the routine fails.
For some corner cases, it is observed that association is failed
even for valid security information based on association history.
This patch fixes the problem by clearing previous security setting
during each association.
We should set WEP key provided in connect request as default tx key.
This missing change is also added here.

After unregistering an hci_dev object a bluetooth driver does not have
any callbacks in the hci_dev structure left over. Therefore, there is no
need to keep a reference to the module.
Previously, we needed this to protect the hci-destruct callback.
However, this callback is no longer available so we do not need this
owner field, anymore. Drivers now call hci_unregister_dev() and they
are done with the object.

We currently leak the hci_uart object if HCI_UART_PROTO_SET is never set
because the hci-destruct callback will then never be called. This fix
removes the hci-destruct callback and frees the driver internal private
hci_uart object directly on tty-close. We call hci_unregister_dev() here
so the hci-core will never call our callbacks again (except destruct).
Therefore, we can safely free the driver internal data right away and
set the destruct callback to NULL.

Instead of waiting for the hdev object to get freed we now free the
private driver-internal data on SDIO shutdown. This allows us to remove
the obsolete hci-destruct callback and free our data object right away
after calling hci_unregister_dev(). The HCI-core does not call any
callbacks after this so we are never called again and can safely exit
the module.

Instead of waiting for the hci-device to be destroyed we now free the
private driver data on driver shutdown right away. We call
hci_unregister_dev() on driver shutdown, that means, the hci-core will
never ever call our callbacks again except the destruct callback. It
also does not access hdev->driver_data so there is no reason to keep
that alive. We simply set the destruct cb to NULL to avoid getting
called again.

Instead of using the hci-destruct callback we free our private driver
data on USB shutdown. We already called hci_unregister_dev() here so the
hci core will never ever call our callbacks again except the destruct
callback.
However, there is no reason to keep our *private* driver data alive if
we get never called again and the hci-core does never touch it the data.
So we simply free it right away and set the destruct callback to NULL.

This frees the private driver data on USB shutdown instead of using the
hci-destruct callback. We already call usb_set_intfdata(intf, NULL) but
we do not do the same with the hci object. This would be totally safe,
though.
After calling hci_unregister_dev()/hci_free_dev() the hdev object will
never call any callback of us again except the destruct callback.
Therefore, we can safely set the destruct callback to NULL and free the
driver data right away. This allows to unload the module without
waiting for the hdev device to be released.

This removes the hci-destruct callback and instead frees the private
driver data in the vhci_release file release function. There is no
reason to keep private driver data available if the driver has already
shut down.
After vhci_release is called our module can be unloaded. The only reason
it is kept alive is the hci-core having a module-ref on us because of
our destruct callback. However, this callback only frees
hdev->driver_data. That is, we wait for the hdev-device to get destroyed
to free our internal driver-data. In fact, the hci-core does never touch
hdev->driver_data so it doesn't care if it is NULL. Therefore, we simply
free it when unloading the driver.
Another important fact is that the hdev core does not call any callbacks
other than the destruct-cb after hci_unregister_dev() has been called.
So there is no function of our module that will be called nor does the
hci-core touch hdev->driver_data. Hence, no other code can touch
hdev->driver_data after our cleanup so the destruct callback is
definitely unnecessary here.

We are getting more and more fields in struct rt2x00_dev that are
specific to one or two of the low-level drivers. Instead of putting
these fields inside the main structure and thus clobbering all low-level
drivers with these fields, introduce the concept of driver data inside
struct rt2x00_dev, whose size is indicated by the low-level driver and
which can be populated by the low-level driver.

Some devices (iwl5100) cannot connect to zd1211rw based AP. It appears that
zd1211 firmware messes up duration_id field if it is not set to zero by driver.
Sniffing traffic shows that zd1211 is transmitting frames with duration_id bits
14 and 15 set and other bits appearing random. Setting duration_id at driver to
zero results zd1211 outputting sane duration_id. This means that firmware is
setting correct values itself and expects duration_id to be zero in first
place.
Looking at vendor driver shows that only PSPoll frames have duration_id set by
driver, for other frames duration_id left zero.
