1. Change first parameter from cnic_dev to ulp_handle which is the hba
pointer. All other similar upcalls are using hba pointer. The callee
can then directly reference the hba without conversion.
2. Change return value from void to int so that an error code can be
passed back. This allows the operation to be retried.

cnic_dev_list is protected by rtnl_lock and cnic_dev_lock spin_lock during
modifications. When looping on cnic_dev_list and calling ->cnic_init(),
we should just hold rtnl_lock since ->cnic_init() may sleep.

If CONFIG_MAC80211_LEDS is not set, ieee80211_i.h was failing to compile,
because struct led_trigger is only declared when CONFIG_LEDS_TRIGGERS is
set.
This patch adds ifdefs around the tpt_led_trigger declaration in
ieee80211_i.h to avoid the problem.

The throughput LED trigger was always active when
the radio was enabled. In most cases that's likely
the desired behaviour, but iwlwifi requires it to
be only active when one of the virtual interfaces
is actually "connected" in some way.

iwlwifi and other drivers like to blink their LED
based on throughput. Implement this generically in
mac80211, based on a throughput table the driver
specifies. That way, drivers can set the blink
frequencies depending on their desired behaviour
and max throughput.
All the drivers need to do is provide an LED class
device, best with blink hardware offload.

The throughput trigger will require doing LED
classdev/trigger handling before register_hw(),
so drivers should have access to the trigger
names before it. If trigger registration fails,
this will still make the trigger name available,
but that's not a big problem since the default
trigger will the simply not be found.

Restricting the chainmask to 1 for legacy mode disables useful features
such as MRC, and it reduces the available transmit power.
I can't think of a good reason to do this in legacy mode, so let's just
get rid of that code.

The commit 'ath9k_hw: Disable PAPRD for rates with low Tx power' changed
the code that sets the PAPRD rate masks to use only either the HT20 mask
or the HT40 mask. This is wrong, as the hardware can still use HT20 rates
even when configured for HT40, and the operating channel mode does not
affect PAPRD operation.
The register for the HT40 rate mask is applied as a mask on top of the
other registers to selectively disable PAPRD for specific rates on HT40
packets only.
This patch changes the code back to the old behavior which matches the
intended use of these registers. While with current cards this should not
make any practical difference (according to Atheros, the HT20 and HT40
mask should always be equal), it is more correct that way, and maybe
the HT40 mask will be used for some rare corner cases in the future.

When an skb is shared, it needs to be duplicated, along with its data buffer.
If the skb does not have enough headroom, using skb_copy might cause the data
buffer to be copied twice (once by skb_copy and once by pskb_expand_head).
Fix this by using skb_clone initially and letting ieee80211_skb_resize sort
out the rest.

When rfkill is enabled, ath9k_hw unnecessarily configured the baseband to
turn off based on GPIO input, however that code was hardcoded to GPIO 0
instead of ah->rfkill_gpio.
Since ath9k uses software rfkill anyway, this code is completely unnecessary
and should be removed in case anything else ever uses GPIO 0.

To improve aggregation length, there should not be more than two fully formed
A-MPDU frames in the hardware queue. To ensure this, the code checks the tx
queue length before forming new A-MPDUs. This can reduce the throughput (or
maybe even starve out A-MPDU traffic) when too many non-aggregated frames are
in the queue.
Fix this by keeping track of pending A-MPDU frames (even when they're sent out
as single frames), but exclude rate control probing frames to improve
performance.

The Mesh Control header only includes 0, 1 or 2 addresses. If there is
one address, it should be interpreted as Address 4. If there are 2,
they are interpreted as Addresses 5 and 6 (Address 4 being the 4th
address in the 802.11 header).
The address extension used to hold up to 3 addresses instead of the current 2.
I'm not sure which draft version changed this, but it is very unlikely that it
will change again given the state of the approval process of this draft. See
section 7.1.3.6.3 in current draft (8.0).
Also, note that the extra address that I'm removing was not being used, so this
change has no effect on over-the-air frame formats. But I thought I better
remove it before someone does start using it.

The old survey implementation was broken and returned nonsense data.
Clear cycle counters and survey data on reset. Since the cycle counters easily
overflow it's better to keep a local version of collected survey data (in ms
resolution, instead of clockrate) and update this every time survey is
retrieved. If survey is retrieved often enough to avoid cycle counter overflows
this works fine, otherwise we could update survey more often, like ath9k does.
Still only the survey for the current channel is kept.

Once we moved the core regulatory request to the queue and let
the scheduler process it last_request will have been left NULL
until the schedular decides to process the first request. When
this happens and we are loading a driver with a custom regulatory
request like all Atheros drivers we end up with a NULL pointer
dereference. We fix this by checking if the request was a
custom one.

Add a new notification to indicate that a received, unprotected
Deauthentication or Disassociation frame was dropped due to
management frame protection being in use. This notification is
needed to allow user space (e.g., wpa_supplicant) to implement
SA Query procedure to recover from association state mismatch
between an AP and STA.
This is needed to avoid getting stuck in non-working state when MFP
(IEEE 802.11w) is used and a protected Deauthentication or
Disassociation frame is dropped for any reason. After that, the
station would silently discard any unprotected Deauthentication or
Disassociation frame that could be indicating that the AP does not
have association for the STA (when the Reason Code would be 6 or 7).
IEEE Std 802.11w-2009, 11.13 describes this recovery mechanism.

Change some file names and Kconfig settings so that this new module matches

Also fix SDIO power enabling and disabling to match the latest way of doing

With the current single-queue implementation traffic priorization is not
working correctly - when using multiple BE streams and one, say VI stream,
the VI stream will share bandwidth almost equally with the BE streams.
To fix the issue, implement per AC queues, which are emptied in priority
order to the firmware. To keep it relatively simple, maintain a global
buffer count and global queue stop/wake instead of per-AC.
With these changes, priorization appears to work just fine.

Currently, the debug level is set in compilation time (by the DEBUG_LEVEL
const). This method has the advantage of compiling only the relevant
messages, while optimizing out the unused ones.
In order to allow runtime control over the debug_level, while optimizing
out messages when debug messages are not needed, we combine some methods:
1. use dynamic_debug (pr_debug) rather then printk.
2. add debug_level module param in order to set debug level during insmod.
3. add debug_level sysfs file in order to allow dynamic control over the
debug level.
Since patches for pr_debug_hex_dump() implementation haven't been applied yet,
we are still temporarly using print_hex_dump().

Inclusion of a WPS IE in probe requests caused a problem
in the driver due to the maximum size of the probe request
template and the max_scan_ie_len values at initialization.
Increased the size of probe request template
to the maximum size allowed by the firmware.
Struct wl12xx_probe_req_template, which was only used
for calculating the max size of the probe request template,
is no longer used and needed.
max_scan_ie_len is used for validating the size of
additional IEs in scan requests.
Initialized the max_scan_ie_len field to the maximum size
of the probe request template minus the ieee80211 header size.

The auto-arp feature of wl12xx allows the firmware to automatically

passing its ip)
