MAC maintains TX FIFO to transmit packets with meta data to BB layer. To
debug abnormal transmission, we need to dump the content to dig problem.
Since FIFO of 8852C locates on different address with different size and
need additional switch to enable read operation, this patch adds the
changes accordingly.

IQK can change the values of this register set, so need to backup and
restore the values. During we rewrite IQK, the policy is changed. Some
values are controlled and filled by IQK, and don't need to restore after
IQK. Therefore, remove this kind of registers from this array.

Auto Channel Select feature of HostAP uses dump_survey to fetch
OBSS statistics. When the device is in the middle of an authentication
sequence or just at the end of authentication completion, running
dump_survey would trigger a channel change. The channel change in-turn
can cause packet loss, resulting in authentication delay. With this change,
dump_survey won't be run when authentication or association is in progress,
hence resolving the issue.

When doing dump_survey, host will call "dump_obss" iovar to firmware
side. Host need to make sure the HW clock in dongle is on, or there is
high probability that firmware gets trap because register or shared
memory access failed. To fix this, we disable mpc when doing dump obss
and set it back after that.

Re-enable the function rtl8xxxu_gen2_report_connect.
It informs the firmware when connecting to a network. This makes the
firmware enable the rate control, which makes the upload faster.
It also informs the firmware when disconnecting from a network. In the
past this made reconnecting impossible because it was sending the
auth on queue 0x7 (TXDESC_QUEUE_VO) instead of queue 0x12
(TXDESC_QUEUE_MGNT):
wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 1/3)
wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 2/3)
wlp0s20f0u3: send auth to 90:55:de:__:__:__ (try 3/3)
wlp0s20f0u3: authentication with 90:55:de:__:__:__ timed out
Probably the firmware disables the unnecessary TX queues when it
knows it's disconnected.
However, this was fixed in commit edd5747aa12e ("wifi: rtl8xxxu: Fix
skb misuse in TX queue selection").

This chip is found in the cheapest USB adapters, e.g. 1.17 USD with
VAT and shipping from China included.
It's a gen 2 chip, similar to the RTL8723BU, but without Bluetooth.
Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps.
The vendor driver rtl8188fu version 4.3.23.6_20964.20170110 [0]
was used as reference. The CD shipped with the device includes a
newer driver, version 5.11.5-1-g12f7cde4b.20201102, but that one
couldn't complete the WPA2 key exchange thing for whatever reason.

Previously, we thought control registers or setting things for TX power
series may change according to chip. So, setting functions are implemented
chip by chip. However, until now, the functions keep the same among chips,
at least 8852A, 8852C, and 8852B. There is a sufficient number of chips to
share generic setting functions. So, we now remake them including TX power
by rate, TX power offset, TX power limit, and TX power limit RU as generic
ones in phy.c.
Besides, there are some code refinements in the generic ones, but almost
all of the logic doesn't change.

The module parameter ht40_2g was supposed to enable 40 MHz operation,
but it didn't.
Tell the firmware about the channel width when updating the rate mask.
This makes it work with my gen 2 chip RTL8188FU.
I'm not sure if anything needs to be done for the gen 1 chips, if 40
MHz channel width already works or not. They update the rate mask with
a different structure which doesn't have a field for the channel width.
Also set the channel width correctly for sta_statistics.

Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length arrays
declarations in anonymous union with the new DECLARE_FLEX_ARRAY()
helper macro.
This helper allows for flexible-array members in unions.

In preparation for reducing the use of ksize(), explicitly track the
size of scan_cmd allocations. This also allows for noticing if the scan
size changes unexpectedly. Note that using ksize() was already incorrect
here, in the sense that ksize() would not match the actual allocation
size, which would trigger future run-time allocation bounds checking.
(In other words, memset() may know how large scan_cmd was allocated for,
but ksize() will return the upper bounds of the actually allocated memory,
causing a run-time warning about an overflow.)

When STA roams from one AP to another, after roam is complete, host
driver tries to get TIM information from firmware. This is no longer
supported in the firmware & hence, this call will always fail.
This failure results in the below message being displayed on the
console all the time when roam is done.
ieee80211 phy0: brcmf_update_bss_info: wl dtim_assoc failed (-52)
Changes ensure that the host driver will no longer try to get TIM
information from firmware.

The bug is here: "} else if (item) {".
The list iterator value will *always* be set and non-NULL by
list_for_each_entry(), so it is incorrect to assume that the iterator
value will be NULL if the list is empty or no element is found in list.
Use a new value 'iter' as the list iterator, while use the old value
'item' as a dedicated pointer to point to the found element, which
1. can fix this bug, due to now 'item' is NULL only if it's not found.
2. do not need to change all the uses of 'item' after the loop.
3. can also limit the scope of the list iterator 'iter' *only inside*
the traversal loop by simply declaring 'iter' inside the loop in the
future, as usage of the iterator outside of the list_for_each_entry
is considered harmful. https://lkml.org/lkml/2022/2/17/1032
