brcmfmac: pcie: Replace brcmf_pcie_copy_mem_todev with memcpy_toio

The alignment check was wrong (e.g. & 4 instead of & 3), and the logic
was also inefficient if the length was not a multiple of 4, since it

brcmfmac: use ISO3166 country code and 0 rev as fallback on some devices

This is a second attempt at honering the country code send out by access
points. This was first added in commit b0b524f079a2 ("brcmfmac: use
ISO3166 country code and 0 rev as fallback").

Subsequently this was reverted in commit 151a7c12c4fc ("Revert "brcmfmac:
use ISO3166 country code and 0 rev as fallback""), because it was causing
issues with AP mode on some brcmfmac models (specifically on BCM4359/9).

Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are
all special world-wide compatibility ccode-s. Most of these world-wide
ccode-s allow passive scan mode only for 2.4GHz channels 12-14,
only enabling them when an AP is seen on them.

But at least on brcmfmac43455 devices this is not working correctly, these
do not see accesspoints on channels 12-14 unless the ccode is changes to
a country where these channels are allowed.

Translating received country codes to an ISO3166 country code and 0 rev
ccreq fixes devices using a brcmfmac43455 with a X2/XT/XU/XV/ALL ccode
not seeing accesspoints on channels 12-14.

To avoid this causing issues on other brcmfmac models again, the
fallback is limited to only brcmfmac4345* chips this time.

rtw89: use hardware SSN to TX management frame

Since firmware transmits beacon by hardware SSN, driver does it with the
same setting, then packets in the air have continual sequence number.

rtw89: correct use of BA CAM

BA CAM is used to ACK peer's packets, so it must be established when
IEEE80211_AMPDU_RX_START, and free it by IEEE80211_AMPDU_RX_STOP.

The hardware can support two static BA CAM entries, so I implement a bitmap
and a struct to record which entry is used and its corresponding tid. Also,
the hardware can learn and create dynamic BA CAM entries automatically if
received packets don't match static BA CAM. That means it can still work if
we don't use H2C to set static BA CAM. An exception is tid=0 should be
always allocated in static BA CAM, so an existing static BA CAM will be
replaced if it is full and peer is going to establish a BA with tid=0.

The new firmware use new format of this H2C, so I upgrade it as well.

rtw89: extract modules by chipset

We are planning to support more chipsets, e.g. 8852C. Before that, we
consider architecutre to handle multiple kinds of chipsets. Obviosuly,
based on original design, rtw89_core module will have large size even
if there is only one chipset under running. It is because all chipset
related things are put in rtw89_core now. To reduce such overhead, we
extract modules of rtw89 and adjust dependencies between modules.

The following assumes that 8852AE, 8852AU, and 8852CE are all supported,
we describe the difference before and after extraction.

[Before extraction]
                                             -------------
       |------------------------------------ | rtw89_usb |
       V                                     -------------
---------------------------------------      -------------
| rtw89_core (including 8852A, 8852C) | <--- | rtw89_pci |
---------------------------------------      -------------
The data of 8852A and 8852C are built in rtw89_core.
And rtw89_pci is the entry of 8852AE and 8852CE.
And rtw89_usb is the entry of 8852AU.

[After extraction]
                    -------------           ----------------
       |----------- | rtw89_usb | <-------- | rtw89_8852au |
       |            -------------           ----------------
       V            ---------------                |
--------------      |             | <---------------
| rtw89_core | <--- | rtw89_8852a |
--------------      |             | <---------------
   ^   ^            ---------------                |
   |   |            -------------           ----------------
   |   |            |           | <-------- | rtw89_8852ae |
   |   |----------- | rtw89_pci |           ----------------
   |                |           | <-----------------
   |                -------------                  |
   |                ---------------         ----------------
   |--------------- | rtw89_8852c | <------ | rtw89_8852ce |
                    ---------------         ----------------
The data of 8852A/8852C is extracted to rtw89_8852a/rtw89_8852c.
And rtw89_pci/rtw89_usb handles only common flow of pci/usb bus.
Finally, 8852AE, 8852AU, and 8852CE have individual entry modules,
i.e. rtw89_8852ae, rtw89_8852au, and rtw89_8852ce correspondingly.

Merge ath-next from git://git./linux/kernel/git/kvalo/ath.git

ath.git patches for v5.18. Major changes:

ath11k

* add LDPC FEC type in 802.11 radiotap header

* enable RX PPDU stats in monitor co-exist mode

wcn36xx

* implement survey reporting

ath11k: avoid firmware crash when reg set for QCA6390/WCN6855

For the NL80211_REGDOM_SET_BY_USER hint from cfg80211, it set the new
alpha2 code to ath11k, then ath11k send WMI_SET_INIT_COUNTRY_CMDID to
firmware for all chips currently. When test with WCN6855/QCA6390 chips,
this WMI CMD leads firmware crash.

For AP based chips(ipq8074/qcn9074), WMI_SET_INIT_COUNTRY_CMDID is used
to send to firmware, for STATION based chips(WCN6855/QCA6390), it need to
use another WMI CMD WMI_SET_CURRENT_COUNTRY_CMDID.

Add flag current_cc_support in hardware parameters, it is used to
distinguish AP/STA platform. After that, the firmware will work
normal and the regulatory feature works well for QCA6390/WCN6855.

ath9k_htc: fix uninit value bugs

Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing
field initialization.

In htc_connect_service() svc_meta_len and pad are not initialized. Based
on code it looks like in current skb there is no service data, so simply
initialize svc_meta_len to 0.

htc_issue_send() does not initialize htc_frame_hdr::control array. Based
on firmware code, it will initialize it by itself, so simply zero whole
array to make KMSAN happy

Merge branch 'udp-ipv6-optimisations'

Pavel Begunkov says:

====================
udp/ipv6 optimisations

Shed some weight from udp/ipv6. Zerocopy benchmarks over dummy showed
~5% tx/s improvement, should be similar for small payload non-zc
cases.

The performance comes from killing 4 atomics and a couple of big struct
memcpy/memset. 1/10 removes a pair of atomics on dst refcounting for
cork->skb setup, 9/10 saves another pair on cork init. 5/10 and 8/10
kill extra 88B memset and memcpy respectively.
