Zero-length arrays as fake flexible arrays are deprecated and we are
moving towards adopting C99 flexible-array members instead.
Address the following warning found with GCC-13 and
-fstrict-flex-arrays=3 enabled:
In function ‘fortify_memset_chk’,
inlined from ‘rtl_usb_probe’ at drivers/net/wireless/realtek/rtlwifi/usb.c:1044:2:
./include/linux/fortify-string.h:430:25: warning: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning]
430 | __write_overflow_field(p_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].

Once beacon content is changed, we update the content to wifi card by
send_beacon_frame(). Then, STA with PS can wake up properly to receive its
packets.
Since we update beacon content to PCI wifi devices every beacon interval,
the only one usb device, 8192CU, needs to update beacon content when
mac80211 calling set_tim.

INIT_DELAYED_WORK() takes two arguments: A pointer to the delayed work and
a function reference for the callback.
The rtl code casts all function references to (void *) because the
callbacks in use are not matching the required function signature. That's
error prone and bad pratice.
Some of the callback functions are also global, but only used in a single
file.
Clean the mess up by:
- Adding the proper arguments to the callback functions and using them in
the container_of() constructs correctly which removes the hideous
container_of_dwork_rtl() macro as well.
- Removing the type cast at the initializers
- Making the unnecessary global functions static

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]
This issue was found with the help of Coccinelle.

The RISC-V architecture has a register named the "Supervisor Exception
Program Counter", or "sepc". This abbreviation triggers checkpatch.pl's
misspelling detector, resulting in noise in the checkpatch output. The
risk that this noise could cause more useful warnings to be missed seems
to outweigh the harm of an occasional misspelling of "spec". Thus drop
the "sepc" entry from the misspelling list.

This driver uses a set of local macros to manipulate the RX and TX
descriptors, which are all little-endian quantities. These macros
are replaced by the bitfield macros le32p_replace_bits() and
le32_get_bits(). In several places, the macros operated on an entire
32-bit word. In these cases, a direct read or replacement is used.

and could be available in other routines. This variable is changed to be

We use 'struct rtl_c2hcmd' to store C2H commands originally, and the code
is slightly complex to enqueue and dequeue and also wastes time to
allocate and memcpy data. Since C2H commands are asynchronous events,
they can be processed in work queue, so RX ISR enqueues C2H result in
removal of rtl_c2h_packet_handler().

In order to realize the keep-alive mechanism in mac80211 stack, reporting
accurate tx ack status for nullfunc frame is added in this commit.
If current frame is nullfunc frame, we ask firmware to report by filling
TX report bit in TX descriptor. After this frame DMA done, TX interrupt is
triggered but TX status is unknown at this moment, so enqueue this skb
into tx_report->queue. Finally, C2H report will be received if the frame
is transmitted successfully or retried over, and then we report to mac80211
with IEEE80211_TX_STAT_ACK flag only if it's successful. Otherwise, if
failure or timeout (one second), we report to mac80211 without this flag.

Some HP laptops have only a single wifi antenna. This would not be a
problem except that they were shipped with an incorrectly encoded
EFUSE. It should have been possible to open the computer and transfer
the antenna connection to the other terminal except that such action
might void the warranty, and moving the antenna broke the Windows
driver. The fix was to add a module option that would override the
EFUSE encoding. That was done with commit c18d8f509571 ("rtlwifi:
rtl8723be: Add antenna select module parameter"). There was still a
problem with Bluetooth coexistence, which was addressed with commit
baa170229095 ("rtlwifi: btcoexist: Implement antenna selection").
There were still problems, thus there were commit 0ff78adeef11
("rtlwifi: rtl8723be: fix ant_sel code") and commit 6d6226928369
("rtlwifi: btcoexist: Fix antenna selection code"). Despite all these
attempts at fixing the problem, the code is not yet right. A proper
fix is important as there are now instances of laptops having
RTL8723DE chips with the same problem.
The module parameter ant_sel is used to control antenna number and path.
At present enum ANT_{X2,X1} is used to define the antenna number, but
this choice is not intuitive, thus change to a new enum ANT_{MAIN,AUX}
to make it more readable. This change showed examples where incorrect
values were used. It was also possible to remove a workaround in
halbtcoutsrc.c.
The experimental results with single antenna connected to specific path
are now as follows:
ant_sel ANT_MAIN(#1) ANT_AUX(#2)
0 -8 -62
1 -62 -10
2 -6 -60

There has been a coding error in rtl8821ae since it was first introduced,
namely that an 8-bit register was read using a 16-bit read in
_rtl8821ae_dbi_read(). This error was fixed with commit 40b368af4b75
("rtlwifi: Fix alignment issues"); however, this change led to
instability in the connection. To restore stability, this change
was reverted in commit b8b8b16352cd ("rtlwifi: rtl8821ae: Fix connection
lost problem").
Unfortunately, the unaligned access causes machine checks in ARM
architecture, and we were finally forced to find the actual cause of the
problem on x86 platforms. Following a suggestion from Pkshih
<pkshih@realtek.com>, it was found that increasing the ASPM L1
latency from 0 to 7 fixed the instability. This parameter was varied to
see if a smaller value would work; however, it appears that 7 is the
safest value. A new symbol is defined for this quantity, thus it can be
easily changed if necessary.

Originally, btcoex controls the antenna of combo card, but solo card
is also needed to setup properly. The new ops are named with suffix
'_wifi_only' opposited to original btc_ops, and new structures and
definitions are also introduced. The wifi_only oly contains four ops that
are initial variable, hw config, scan notify, and switch band notify.

After mac power-on sequence, wifi will start to work so notify btcoex the
event to configure registers especially related to antenna. This will not
only help to assign antenna but also to yield better user experience.
