When chip's temperature is changed, RF characters are changed. To keep the
characters to be consistent, 8723d uses thermal meter to assist in
calibrating LCK, IQK, crystal and TX power.

A base thermal value is programmed in efuse, all calibration data in
MP process is based on this thermal value. So we calucate the delta of
thermal value between the base value, and use this delta to reference XTAL
and TX power offset tables to know how much we need to adjust.

For IQK and LCK, driver checks if delta of thermal value is over 8, then
they are triggered.

For crystal adjustment, when delta of thermal value is changed, we check
XTAL tables to get offset of XTAL value. If thermal value is larger than
base value, positive table (_p as suffix) is used. Otherwise, we use
negative table (_n as suffix). Then, we add offset to XTAL default value
programmed in efuse, and write sum value to register.

To compensate TX power, there are two hierarchical tables. First level use
delta of thermal value to access eight tables to yield delta of TX power
index. Then, plus base TX power index to get index of BB swing table
(second level tables) where register value is induced.

BB swing table can't deal with all cases, if index of BB swing table is
over the size of the table. In this case, TX AGC is used to compensate the
remnant part. Assume 'upper' is the upper bound of BB swing table, and
'target' is the desired index. Then, we can illustrate them as

  compensation method    BB swing        TX AGC
  -------------------    --------    --------------
  target > upper         upper       target - upper
  target < 0             0           target
  otherwise              target      0

For debug purpose, add a column 'rem' to tx_pwr_tbl entry, and it looks
like

  path rate       pwr       base      (byr  lmt ) rem
    A  CCK_1M     32(0x20)   34   -2 (   0   -2)    0

IQ calibration is used to calibrate RF characteristic to yield expected
performance. Basically, we do calibration twice and compare the similarity
to determine calibration is good or not, if not we do the third
calibration, and then compare with the results of first and second
calibration. If it still not similar, IQK is failed.

Before doing calibration, we need to backup registers that will be
modified in calibration procedure, and restore these registers after
calibration is done.

A calibration procedure can divided into four sub-procedures that are
S1-TX, S1-RX, S0-TX and S0-RX. Where, S1 and S0 represent to path A and B
respectively. Each sub-procedure configure proper registers, and then
rigger one-shot calibration and poll until completion. For RX calibration,
it needs to do twice one-shot calibration, first one is to yield parameter
used by second one.

The result of TX part is stored for TX power tracking that adjusts TX AGC
to output expected power.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

caps_buf is always of size sizeof(*caps) because
sizeof(caps->auth_encr_pair) * 16 is always zero. Notice
that when using zero-length arrays, sizeof evaluates to zero[1].

So, the code introduced by
commit 0308383f ("rndis_wlan: get max_num_pmkids from device")
is logically dead, hence is never executed and can be removed. As a
consequence, the rest of the related code can be refactored a bit.

In WLAN, priority among various access categories of traffic is

In this change, priority is adjusted based on the AP WMM params
received as part of the Assoc Response and the same is later used
to map the priority of all incoming traffic.

In a specific scenario where EDCA parameters are configured to be same
for all ACs, use the default FW priority definition to avoid queuing
packets of all ACs to the same priority queue.

By providing more accurate status, TCP stack can avoid adding more

Currently, bonding always returns NETDEV_TX_OK to its caller.

It is worth trying to be more accurate : TCP for instance
can have different recovery strategies if it can have more

The MCU CPSW expected to populate only MDIO device, but follow up patches
will add "compatible" property to the MCU CPSW CPTS node which will cause
creation of CPTS device and MCU CPSW init failure. Hence, switch to use
of_platform_device_create() instead of of_platform_populate() for MDIO
device population.

====================
hsr: hsr code refactoring

There are some unnecessary routine in the hsr module.
This patch removes these routines.

The first patch removes incorrect comment.
The second patch removes unnecessary WARN_ONCE() macro.

Create an independent function that takes a particular frame queue and
an array of frame descriptors and tries to enqueue them until it hits
the maximum number fo retries. The same function will be used in the
next patch also on the XDP_TX path.

Also, create the dpaa2_eth_xdp_fds structure to incorporate the array of
FDs as well as the number of FDs already populated.

When VLAN frame is being sent, hsr calls WARN_ONCE() because hsr doesn't
support VLAN. But using WARN_ONCE() is overdoing.
Using netdev_warn_once() is enough.

Mask the consumer index before using it. Without this, we would be
writing frame descriptors beyond the ring size supported by the QBMAN
block.

Add some verbiage describing how the hardware features of the switch are
exposed to users through tc-flower.
