In driver rtlwifi, efuse_read() places two relatively large arrays on the
stack - a 1D u8 array of size 128, and a 2D array of u16 with 128 * 4 elements.
With driver rtl8192de, the sizes will be 256 and 256 * 4 respectively. As that
will make the 2D array be 2048 bytes, I have changed the code to use kmalloc to
allocate the space.

The function iwl_is_any_associated() was intended
to check both contexts, but due to an oversight
it only checks the BSS context. This leads to a
problem with scanning since the passive dwell
time isn't restricted appropriately and a scan
that includes passive channels will never finish
if only the PAN context is associated since the
default dwell time of 120ms won't fit into the
normal 100 TU DTIM interval.

Fix the function by using for_each_context() and
also reorganise the other functions a bit to take
advantage of each other making the code easier to
read.

This patch adds the feature to support the test mode operation through
the generic netlink channel NL80211_CMD_TESTMODE between intel
wireless device iwlwifi and the user space application svtool.

The main purpose is to create a transportation layer between the iwlwifi
device and the user space application so that the interaction between the
user space application svtool and the iwlwifi device in the kernel space is
in a way of generic netlink messaging.

The detail specific functions are:

1. The function iwl_testmode_cmd() is added to digest the svtool test command
   from the user space application. The svtool test commands are categorized  to
   three types : commands to be processed by the device ucode, commands to access
   the registers, and commands to be processed at the driver level(such as reload
   the ucode). iwl_testmode_cmd() dispatches the commands the corresponding handlers
   and reply to user space regarding the command execution status. Extra data is
   returned to the user space application if there's any.

2. The function iwl_testmode_ucode_rx_pkt() is added to multicast all the spontaneous
   messages from the iwlwifi device to the user space. Regardless the message types,
   whenever there is a valid spontaneous message received by the iwlwifi ISR,
   iwl_testmode_ucode_rx_pkt() is invoked to multicast the message content to user
   space. The message content is not attacked and the message parsing is left to
   the user space application.

Implementation guidelines:

1. The generic netlink messaging for iwliwif test mode is through  NL80211_CMD_TESTMODE
   channel, therefore, the codes need to follow the regulations set by cfg80211.ko
   to get the actual device instance ieee80211_ops via cfg80211.ko, so that the iwlwifi
   device is indicated with ieee80211_ops and can be actually accessed.

   Therefore, a callback iwl_testmode_cmd() is added to the structure
   iwlagn_hw_ops in iwl-agn.c.

2. It intends to utilize those low level device access APIs from iwlwifi device driver
   (ie. iwlagn.ko) rather than creating it's own set of device access functions.
   For example, iwl_send_cmd(), iwl_read32(), iwl_write8(), and iwl_write32() are reused.

3. The main functions are maintained in new files instead of spreading all over the
   existing iwlwifi driver files.

   The new files added are :

   drivers/net/wireless/iwlwifi/iwl-sv-open.c
        - to handle the user space test mode application command
          and reply the respective command status to the user space application.
        - to multicast the spontaneous messages from device to user space.

        - the commonly referenced definitions for the TLVs used in
          the generic netlink messages

With AR9003 at about ~ 10 feet from an AP that uses RTS / CTS you
will be able to associate but not not get data through given that
the power for the rates used was set too low. This increases the
power and permits data connectivity at longer distances from
access points when connected with HT40. Without this you will not
get any data through when associated to APs configured in HT40
at about more than 10 feet away.

  commit: 10e11568

introduced a severe regression on the throughput
for USB hardware. It turns out that the exiting of

The exact cause for this regression is unknown,

seems to resolve the issue.

At present the noise floor calibration is processed in supported
control and extension chains rather than required chains.
Unnccesarily doing nfcal in all supported chains leads to
invalid nf readings on extn chains and these invalid values
got updated into history buffer. While loading those values
from history buffer is moving the chip to deaf state.

This issue was observed in AR9002/AR9003 chips while doing
associate/dissociate in HT40 mode and interface up/down
in iterative manner. After some iterations, the chip was moved
to deaf state. Somehow the pci devices are recovered by poll work
after chip reset. Raading the nf values in all supported extension chains
when the hw is not yet configured in HT40 mode results invalid values.

Currently, the driver only disable multicast filtering when the
FIF_ALLMULTI driver flag has been just set (ie,
if changed_flags& FIF_ALLMULTI and *new_flags& FIF_ALLMULTI) or else
it will reenable multicast filtering.

But next time, this condition will be false and multicast filtering
will be reenabled, even through FIF_ALLMULTI is still set.

This mean that allmulticast only works for less than two minutes in
ad-hoc mode.  This patch fixes that to disable multicast filtering
as long as FIF_ALLMULTI is set.

Commit dbd2fd65 added a mechanism for
user space to indicate whether a default key is being configured for
only unicast or only multicast frames instead of all frames. This
commit added a driver capability flag for indicating whether separate
default keys are supported and validation of the set_key command based
on that capability.

However, this single capability flag is not enough to cover possible
difference based on mode (AP/IBSS/STA) and the way this change was
introduced resulted in a regression with drivers that do not indicate
the new capability (i.e.., more or less any non-mac80211 driver using
cfg80211) when using a recent wpa_supplicant snapshot.

Fix the regression by removing the new check which is not strictly
speaking needed. The new separate default key functionality is needed
only for RSN IBSS which has a separate capability indication.

scenario even if the common routine is called for scan ioctl
