_rtl8821ae_clear_pci_pme_status() accesses the upper byte of the Power
Management Control/Status register (PMCS) with literal 5 offset.
Access the entire PMCS register using defines from pci_regs.h to
improve code readability.
While at it, remove the obvious comment and tweak debug prints
slightly to not sound misleading.

Instead of open coding the capability structure search, find the PM
Capability using pci_find_capability().
While at it, rename the generic 'cap_pointer' to 'pm_cap' which makes
the intent of the code more obvious.

It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled. All the SKBs have
been dequeued from the old queue, so it's safe to enqueue these
SKBs to a free queue, then free them after spin_unlock_irqrestore()
at once. Compile tested only.

Currently in mac80211 each STA object is represented
using sta_info datastructure with the associated
STA specific information and drivers access ieee80211_sta
part of it.
With MLO (Multi Link Operation) support being added
in 802.11be standard, though the association is logically
with a single Multi Link capable STA, at the physical level
communication can happen via different advertised
links (uniquely identified by Channel, operating class,
BSSID) and hence the need to handle multiple link
STA parameters within a composite sta_info object
called the MLD STA. The different link STA part of
MLD STA are identified using the link address which can
be same or different as the MLD STA address and unique
link id based on the link vif.
To support extension of such a model, the sta_info
datastructure is modified to hold multiple link STA
objects with link specific params currently within
sta_info moved to this new structure. Similarly this is
done for ieee80211_sta as well which will be accessed
within mac80211 as well as by drivers, hence trivial
driver changes are expected to support this.
For current non MLO supported drivers, only one link STA
is present and link information is accessed via 'deflink'
member.
For MLO drivers, we still need to define the APIs etc. to
get the correct link ID and access the correct part of
the station info.
Currently in mac80211, all link STA info are accessed directly
via deflink. These will be updated to access via link pointers
indexed by link id with MLO support patches, with link id
being 0 for non MLO supported cases.
Except for couple of macro related changes, below spatch takes
care of updating mac80211 and driver code to access to the
link STA info via deflink.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
The only file where some GFP_ flags are updated is 'pci.c'.
When memory is allocated in '_rtl_pci_init_tx_ring()' and
'_rtl_pci_init_rx_ring()' GFP_KERNEL can be used because both functions are
called from a probe function and no spinlock is taken.
The call chain is:
rtl_pci_probe
--> rtl_pci_init
--> _rtl_pci_init_trx_ring
--> _rtl_pci_init_rx_ring
--> _rtl_pci_init_tx_ring

Function _rtl8821ae_mrate_idx_to_arfr_id is functionally identical to
the generic version rtl_mrate_idx_to_arfr_id, so remove
_rtl8821ae_mrate_idx_to_arfr_id and use the generic one instead.
This also fixes a missing break statement found by CoverityScan in
_rtl8821ae_mrate_idx_to_arfr_id, namely: CID#1167237 ("Missing break

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.

With the RTL8822BE and later devices, the number of interrupt vectors
has grown from 2 to 4. At this point, saving and passing those vectors
in a struct makes more sense than using individual scaler variables.
In two of the drivers, code to process the second of the interrupt
registers was included, but commented out. This patch removes those

Presumably the value of rtlhal->last_suspend_sec is not all that
important, but it does get used, so we probably want the

The better fix of relocating the critical variables into struct rtl_priv

alignment to access registers. This change contains the following:
1. Function _rtl8821ae_dbi_read() is used to read one byte from DBI,
thus it should use rtl_read_byte().
2. Register 0x4C7 of 8192ee is single byte.

This patch also fixes two places in each of rtl8192ee, rtl8723be,
and rtl8821ae where the logical condition was incorrect.

RT_TRACE does not add a newline to the end of a message and always
emits at KERN_DEBUG so these are susceptible to message interleaving
from other processes without the newline.

There are nine copies of the _rtl88ee_read_adapter_info() function,
and most but not all of them cause a build warning in some configurations:
rtl8192de/hw.c: In function '_rtl92de_read_adapter_info':
rtl8192de/hw.c:1767:12: error: 'hwinfo' may be used uninitialized in this function [-Werror=maybe-uninitialized]
rtl8723ae/hw.c: In function '_rtl8723e_read_adapter_info.constprop':
rtlwifi/rtl8723ae/hw.c:1654:12: error: 'hwinfo' may be used uninitialized in this function [-Werror=maybe-uninitialized]
The problem is that when rtlefuse->epromtype is something other than
EEPROM_BOOT_EFUSE, the rest of the function uses undefined data, resulting
in random behavior later.
Apparently, in some drivers, the problem was already found and fixed
but the fix did not make it into the others.
This picks one approach to deal with the problem and applies identical
code to all 9 files, to simplify the later consolidation of those.

Smatch reports the following warning:
CHECK drivers/net/wireless/realtek/rtlwifi/rc.c
drivers/net/wireless/realtek/rtlwifi/rc.c:144 _rtl_rc_rate_set_series() warn: impossible condition '(wireless_mode == 256) => (0-255 == 256)'
This warning arises because commit acc6907b87a9 ("rtlwifi: Fix warning
from ieee80211_get_tx_rates() when using 5G") now checks the wireless
mode for WIRELESS_MODE_AC_ONLY (BIT(8)) in _rtl_rc_rate_set_series().
As a result, all quantities used to store the wireless mode must be u16.
This patch also reorders struct rtl_sta_info to save a little space.

There are several copies of the 5G channel tables in this driver. These
are removed so that the tables in the core will be used. This change
also removes a useless message of "Channel 163 in Group not found".
The number of possible 5G channels was reduced from 54 to a better
value of 49 during the conversion.

In commit 54328e64047a5 ("rtlwifi: rtl8821ae: Fix system lockups on boot"),
an attempt was made to fix a regression introduced in commit 1277fa2ab2f9
("rtlwifi: Remove the clear interrupt routine from all drivers").
Unfortunately, there were logic errors in that patch that prevented
affected boxes from booting even after that patch was applied.
The actual cause of the original problem is unknown as none of the
developers have systems that are affected.

Kalle Valo says:
====================
here's a bigger pull request for 4.4. The diffstat looks scary as we
created a new directory realtek for all realtek drivers. In the future
I'm planning to create similar directories for all vendors, currently we
just have ath, mediatek and realtek. This change has been in linux-next
for a couple of weeks so it should be safe, but of course you never
know.
There's also a new driver rtl8xxxu for few realtek USB devices. This
just made it to the last linux-next build.
Otherwise there's nothing really special, more info below. If time
permits, and it's ok for you, I'm hoping to send you a one more pull
request this week.
brcmfmac
* using netdev carrier state
* add and rework some cfg80211 callbacks mainly for AP mode
* use devcoredump when triggered by firmware event
realtek
* create new directory drivers/net/wireless/realtek/ for all realtek
drivers, not visible to users (no kconfig changes etc)
* add rtl8xxxu, a new mac80211 driver for RTL8723AU, RTL8188CU,
RTL8188RU, RTL8191CU, RTL8192CU and hopefully more in the future
ath10k
* add board 2 API support for automatically choosing correct board file
* data path optimisations
* disable PCI power save for qca988x and QCA99x0 due to interop reasons
wil6210
* BlockAckReq support
* firmware crashdump using devcoredump
* capture all frames with sniffer

Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.
