This allows individual users and deployments to disable mesh support at

Some of the BCM43xx chips contain cores that are attached to the SSB, but are
inactive as they do not connect to the external environment. These must not be
registered. Several of these types are handled in driver ssb; however, the
specific case of an inactive 802.11 cores is now treated in b43 and b43legacy.
Although the current setup works, this minor change will place all such
workarounds in ssb, and simplify the code in drivers b43 and b43legacy.

The structure definition is
struct mwifiex_opt_sleep_confirm_buffer {
u8 hdr[4];
struct mwifiex_opt_sleep_confirm ps_cfm_sleep;
} __packed;
For sleep_confirm command we already reserve 4 bytes (using skb_reserve())
for an interface header. It will be filled later by interface specific code.
We don't need "hdr[4]" element in above structure. So we can use
"struct mwifiex_opt_sleep_confirm" directly instead of
"struct mwifiex_opt_sleep_confirm_buffer".

Broadcom has released cards based on a new AMBA-based bus type. From a
programming point of view, this new bus type differs from AMBA and does
not use AMBA common registers. It also differs enough from SSB. We
decided that a new bus driver is needed to keep the code clean.
In its current form, the driver detects devices present on the bus and
registers them in the system. It allows registering BCMA drivers for
specified bus devices and provides them basic operations. The bus driver
itself includes two important bus managing drivers: ChipCommon core
driver and PCI(c) core driver. They are early used to allow correct
initialization.
Currently code is limited to supporting buses on PCI(e) devices, however
the driver is designed to be used also on other hosts. The host
abstraction layer is implemented and already used for PCI(e).
Support for PCI(e) hosts is working and seems to be stable (access to
80211 core was tested successfully on a few devices). We can still
optimize it by using some fixed windows, but this can be done later
without affecting any external code. Windows are just ranges in MMIO
used for accessing cores on the bus.

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.

The assumsion is that while processing ath9k tasklet,
interrupts were already disabled and it will be enabled
at the completion of ath9k tasklet. But whenever TSFOOR is raised,
the driver configures the beacon timers after having received a
beacon frame from the AP which inturn enables the interrupts.

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.
drivers/net/wireless/iwlwifi/iwl-testmode.h
- the commonly referenced definitions for the TLVs used in
the generic netlink messages

Since firmware is capable of generating IV's for all crypto
suits (TKIP, CCMP and WEP), do not ask mac80211 to generate
IV when HW crypto is being used. Instead only reserve
appropriate space in tx skb's in the driver, so that the
firmware can write IV's values.

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.

Patch:
rt2x00: Make rt2x00_queue_entry_for_each more flexible
commit: 10e11568ca8b8a15f7478f6a4ceebabcbdba1018
introduced a severe regression on the throughput

The exact cause for this regression is unknown,
but by disabling the premature exiting of the loop
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.
