This patch fixes multiple issues with the current RTT
implementation in ath9k.
* The data that is obtained from the RTT interface registers
are stored in 31:5 - mask out the extra bits when reading them.
* A history buffer is maintained which is not needed at all.
Remove this array and just store the baseband data for each
chain (or bank).
* A 'num_readings' variable was being used to handle the
last entry. But it was being used in an improper manner, with
the result that the RTT values were never being written
to the RTT Interface registers. Fix this by using a simple
flag.
* Stop baseband operations before programming the calibration values
to the HW.
* Do not restore RX gain settings as part of RTT.

Drivers need to report the number of transmission attempts for each rate
as well as to terminate the rate array with -1. The in-kernel datapath
of hwsim simulates a perfect medium, therefore the driver only needs to
report that the first transmission attempt was sucessfully completed at
the most favorable rate.
Rate control is working again for this driver. Tested mesh mode with
minstrel.

In commit b0302ab, the rtlwifi family of drivers was converted to use
asynchronous firmware loading. Unfortumately, the implementation was
racy, and the ieee80211 routines could be started before rtl_init_core()
was called to setup the data.
This patch fixes the bug noted in https://bugzilla.kernel.org/show_bug.cgi?id=43187.

Some sdio host controllers do not support real in band interrupt.
Software polling mode as a replacement is not fast enough for
high throughput and new features. Also some in band interrupts
do not support host wake up on embedded platform even when they
are real physical interrupts. Therefore out of band (oob)
interrupt mechanism is implemented for these scenarios.
To provide oob irq number and flags used for irq registration in
brcmfmac, a platform device contains irq resource must be
registered in board specific code.
Here is an example of platform device structure:
struct resource brcmf_sdio_res[] = {
{
.start = GPIO_BRCMF_SDIO_OOB_NUM,
.end = GPIO_BRCMF_SDIO_OOB_NUM,
.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,
}
};
struct platform_device brcmf_sdio_device = {
.name = "brcmf_sdio_pd",
.id = -1,
.num_resources = ARRAY_SIZE(brcmf_sdio_res),
.resource = brcmf_sdio_res,
};

By default, iwlwifi uses order-1 pages (8 KB) to store incoming frames,
but doesnt say so in skb->truesize.
This makes very possible to exhaust kernel memory since these skb evade
normal socket memory accounting.
As struct ieee80211_hdr is going to be pulled before calling IP stack,
there is no need to use dev_alloc_skb() to reserve NET_SKB_PAD bytes.
alloc_skb() is ok in this driver, allowing more tailroom.
Pull beginning of frame in skb header, in the hope we can reuse order-1
pages in the driver immediately for small frames and reduce their
truesize to the minimum (linear skbs)

This reverts commit a844adfd7b.
The commit a844adfd is degrading rx sensitivity of lower rate in
HT40 mode and it is confirmed that reverting the change is
improving rx sensitivity.
spur_freq_sd (for self-corr in AGC) is defined with respect to the
center of each 20MHz channel while spur_phase_delta (for self-corr
in Rx and spur data filter) is defined with respect to the center
of current RF channel.
So in short, we need to subtract spur_freq_sd (for self-corr in AGC)
by the offset between the center of primary20 and the center of RF
channel in SW. This offset could be +/10 MHz for dynamic 40.

Newer devices have 20 (5000 series) or 30 (6000 series)
hardware queues, rather than the 16 that 4965 had. This
was added to the driver a long time ago, but improperly:
the queue registers for the higher queues aren't just
continuations of the registers for the first 16 queues,
they are in other places. Therefore, the hardware would
lock up when trying to activate queue 16 or above and
the device would have to be restarted.
Thanks goes to Emmanuel who identified this and told me
how the queue programming should be done.
Note that we don't use queues 20 and higher today and
doing so needs more work than this.

Fix merge between commit 3adadc08cc ("net ax25: Reorder ax25_exit to
remove races") and commit 0ca7a4c87d ("net ax25: Simplify and
cleanup the ax25 sysctl handling")
The former moved around the sysctl register/unregister calls, the
later simply removed them.
With help from Stephen Rothwell.

For now at least, all module parameters should be
with the core functionality, so move them there,
while at it rename to iwlwifi_mod_params. Also
rename iwl-shared.h to iwl-modparams.h to reflect
the real contents.

A workaround in commit c0486b7ccc5 resulted in a 40% drop in receive
throughput in order to fix a transmit problem. The transmit problem
no longer occurs, so restore the receive throughput.

Since the transport allocates and frees itself in
the transport specific code, there's no need for
virtual functions for it. Remove the free method
and call the correct functions directly.

We can't get rid of everything yet due to
the BT definitions that I'm not quite sure
yet how to handle, but we can get rid of
most unneeded includes.

Since the PCI core shouldn't include the
iwl-eeprom.h header file, move the OTP
definitions into iwl-agn-hw.h which can
be included.

The hardware files belong to the core PCI
functionality, but the eeprom header file
mixes higher-level functionality and the
defines, so move out the specific defines
and put them into the appropriate HW files
instead.

These defines will have to be shared
between modules, but they seem better

We only need one declaration, not multiple.
Keep the one in iwl-shared.h, which will
probably be renamed to iwl-modparams.h at
some point in the future.

Keeping statistics per frame type really isn't
very useful, and needs a huge amount of code
so remove it. Since that is the only thing in
iwl-core.{c,h} now, those files can be killed.

That file is now holding just a few defines and
the module parameters, so it shouldn't include
anything. Make sure the right users include the
right files instead.
