Report chains and chain_signal in ieee80211_rx_status.
It is useful for program such as tcpdump to see if the
antennas are well connected/placed.
8822C is able to receive CCK rates with 2 antennas, while
8822B can only use 1 antenna path to receive CCK rates.

This mechanism reduces the numbers of false alram in cck rate by
dynamically adjusting the value of power threshold and cs_ratio.
We determine the new value by three factors, which are rssi, false alarm
count and igi. Based on these factors, we define the current condition
into five levels. Compared to the previous level, if the level is changed,
we set the new values for power threshold and cs_ratio.

Since 8822c requires to do not only IQK, but also DPK.
Move these calibrations that need to be done once the channel
is determined, into phy_calibration.
And note that the order of the calibrations matters, 8822c
should do IQK first, then DPK.

Power amplifiers are not linear components, and require DPK to
reduce its nonlinearity. DPK is called Digital Pre-distortion
Calibration, can be used to compensate the output of power.
DPK tracking is in charge of tracking the thermal changes. And
it then shifts the power curve accordingly, which makes the
power output remains linear even if the PA works in different
temperature.
To perform DPK, the parameter table should also be updated.
And the table will be applied when device is powered on.
Then DPK will reference the values to calibrate.

Add support for doing IQK in firmware
Ideally the RF component's I/Q vectors should be orthogonal,
but usually they are not. So we need to calibrate for the RF
components, ex. PA/LNA, ADC/DAC.
And if the I/Q vectors are more orthogonal, the mixed signal
will have less deviation. This helps with those rates with
higher modulation (MCS8-9), because they have more strict
EVM/SNR requirement. Also the better of the quality of the
signal, the longer it can propagate, and the better throughput
performance we can get.

The problem is that the Tegra PCIe driver indirectly uses I2C for
controlling some regulators and the I2C driver is now being suspended
before the PCIe driver causing the PCIe suspend to fail. The Tegra PCIe
driver is suspended during the NOIRQ phase and this cannot be changed
due to other dependencies. Therefore, we also need to move the suspend
handling for the Tegra I2C driver to the NOIRQ phase as well.
In order to move the I2C suspend handling to the NOIRQ phase we also
need to avoid calling pm_runtime_get/put() because per commit
1e2ef05bb8cf ("PM: Limit race conditions between runtime PM and system
sleep (v2)") these cannot be called early in resume. The function
tegra_i2c_init(), called during resume, calls pm_runtime_get/put() and
so move these calls outside of tegra_i2c_init(), so this function can
be used during the NOIRQ resume phase.

Port the same fix for ixgbe to ixgbevf.
The ixgbevf driver currently does IPsec Tx offloading
based on an existing secpath. However, the secpath
can also come from the Rx side, in this case it is
misinterpreted for Tx offload and the packets are
dropped with a "bad sa_idx" error. Fix this by using
the xfrm_offload() function to test for Tx offload.

100GbE Intel Wired LAN Driver Updates 2019-09-12
This series contains updates to ice driver to implement and support
loading a Dynamic Device Personalization (DDP) package from lib/firmware
onto the device.
Paul updates the way the driver version is stored in the driver so that
we can pass the driver version to the firmware. Passing of the driver
version to the firmware is needed for the DDP package to ensure we have
the appropriate support in the driver for the features in the package.
Lukasz fixes how the firmware version is stored to align with how the
firmware stores its own version. Also extended the log message to
display additional useful information such as NVM version, API patch
information and firmware build hash.
Tony adds the needed driver support to check, load and store the DDP
package. Also add support for the ability to load DDP packages intended
for specific hardware devices, as well as what to do when loading of the
DDP package fails to load.

Intel Wired LAN Driver Updates 2019-09-11
This series contains updates to i40e, ixgbe/vf and iavf.
Wenwen Wang fixes a potential memory leak where 3 allocated variables
are not properly cleaned up on failure for ixgbe.
Stefan Assmann fixes a potential kernel panic found when repeatedly
spawning and destroying VFs in i40e when a NULL pointer is dereferenced
due to a race condition. Fixed up the i40e driver to clear the
__I40E_VIRTCHNL_OP_PENDING bit before returning after an invalid
minimum transmit rate is requested. Updates the iavf driver to only
apply the MAC address change when the PF ACK's the requested change.
Tonghao Zhang updates ixgbe to use the skb_get_queue_mapping() API call
instead of the driver accessing the queue mapping directly.
Jake updates i40e to use ktime_get_real_ts64() instead of
ktime_to_timespec64(). Removes the define for bit 0x0001 for cloud
filters, since it is a reserved bit and not a valid type. Also added
code comments to clearly state which bits are reserved and should not be
used or defined for cloud filter adminq command. Clarify the macros
used to specify the cloud filter fields are individual bits, so use the
BIT() macro.
Aleksandr fixes up the print_link_message() to include the "negotiated"
FEC status for i40e.
Czeslaw also adds additional log message for devices without FEC in the
print_link_message() for i40e.
Colin Ian King reduces the object code size by making the array API
static constant.
Magnus fixes a potential receive buffer starvation issue for AF_XDP by
kicking the NAPI context of any queue with an attached AF_XDP zero-copy
socket.

configuration problems for some users (supplicant and authenticators).
Sticking to the existing wiphy should make error recovery much simpler
and more reliable.

Move code allocating/freeing wiphy out of above functions. This will
allow reinitializing the driver (e.g. on some error) without allocating
a new wiphy.

This moves "ops" pointer from "struct brcmf_cfg80211_info" to the
"struct brcmf_pub". This movement makes it possible to allocate wiphy
without attaching cfg80211 (brcmf_cfg80211_attach()). It's required for
later separation of wiphy allocation and driver initialization.
While at it fix also an unlikely memory leak in the brcmf_attach().

Hi i tried to use the uart_C of the the odroid-c2.
I enabled it in the dts file. During boot it crashed when the
the sdcard slot is addressed.
After long search in the net i found this:
https://forum.odroid.com/viewtopic.php?f=139&t=25371&p=194370&hilit=uart_C#p177856
After changing the pin definitions accordingly erverything works.
Uart_c is functioning and sdcard ist working.

Accessing the device when it may be runtime suspended is a bug, which is
the case in tmio_mmc_host_remove(). Let's fix the behaviour.

The tmio_mmc_host_probe() calls pm_runtime_set_active() to update the
runtime PM status of the device, as to make it reflect the current status
of the HW. This works fine for most cases, but unfortunate not for all.
Especially, there is a generic problem when the device has a genpd attached
and that genpd have the ->start|stop() callbacks assigned.
More precisely, if the driver calls pm_runtime_set_active() during
->probe(), genpd does not get to invoke the ->start() callback for it,
which means the HW isn't really fully powered on. Furthermore, in the next
phase, when the device becomes runtime suspended, genpd will invoke the
->stop() callback for it, potentially leading to usage count imbalance
problems, depending on what's implemented behind the callbacks of course.
To fix this problem, convert to call pm_runtime_get_sync() from
tmio_mmc_host_probe() rather than pm_runtime_set_active(). Additionally, to
avoid bumping usage counters and unnecessary re-initializing the HW the
first time the tmio driver's ->runtime_resume() callback is called,
introduce a state flag to keeping track of this.

This reverts commit 7ff213193310ef8d0ee5f04f79d791210787ac2c.
It turns out that the above commit introduces other problems. For example,
calling pm_runtime_set_active() must not be done prior calling
pm_runtime_enable() as that makes it fail. This leads to additional
problems, such as clock enables being wrongly balanced.
Rather than fixing the problem on top, let's start over by doing a revert.

While storing an int in a pointer is safe the compiler is not
happy about it. So we need some extra casting in order to make
this warning free.
