Commit c134d1f8c436 ("ath11k: Handle errors if peer creation fails") completely
broke AP mode on QCA6390:
kernel: [ 151.230734] ath11k_pci 0000:06:00.0: failed to create peer after vdev start delay: -22
wpa_supplicant[2307]: Failed to set beacon parameters

wpa_supplicant[2307]: wlan0: AP-DISABLED
wpa_supplicant[2307]: wlan0: Unable to setup interface.
wpa_supplicant[2307]: Failed to initialize AP interface
This was because commit c134d1f8c436 ("ath11k: Handle errors if peer creation
fails") added error handling for ath11k_peer_create(), which had been failing
all along but was unnoticed due to the missing error handling. The actual bug
was introduced already in commit aa44b2f3ecd4 ("ath11k: start vdev if a bss peer is
already created").
ath11k_peer_create() was failing because for AP mode the peer is created
already earlier op_add_interface() and we should skip creation here, but the
check for modes was wrong. Fixing that makes AP mode work again.
This shouldn't affect IPQ8074 nor QCN9074 as they have hw_params.vdev_start_delay disabled.

For QCA6390, bss peer must be created before vdev is to start. This
change is to start vdev if a bss peer is created. Otherwise, ath11k
delays to start vdev.
This fixes an issue in a case where HT/VHT/HE settings change between
authentication and association, e.g., due to the user space request
to disable HT.

Problem is that the state of ath11k_skb_cb->flags must be considered
unknown and could contain anything when it is not manually initialized. So
it could also contain ATH11K_SKB_HW_80211_ENCAP. And this can result in the
code to assume that the ath11k_skb_cb->vif is set - even when this is not
always the case for non ATH11K_SKB_HW_80211_ENCAP transmissions.

[ Upstream commit f4d291b43f809b74c66b21f5190cd578af43070b ]
The driver_data area of ieee80211_tx_info is used in ath11k for
ath11k_skb_cb. The first function in the TX patch which rewrites it to
ath11k_skb_cb is already ath11k_mac_op_tx. No one else in the code path
must use it for something else before it reinitializes it. Otherwise the
data has to be considered uninitialized or corrupt.
But the ieee80211_tx_info.control shares exactly the same area as
ieee80211_tx_info.driver_data and ath11k is still using it. This results in
best case in a
ath11k c000000.wifi1: no vif found for mgmt frame, flags 0x0
or (slightly worse) in a kernel oops.
Instead, the interesting data must be moved first into the ath11k_skb_cb
and ieee80211_tx_info.control must then not be used anymore.

The ath11k code will try to insert wheather rader related limits when the
DFS region is set to ETSI. For this reason, it will add two more entries in
the array of reg_rules. But the 2.4.0.1 firmware is prefiltering the list
of reg rules it returns for 2.4GHz PHYs. They will then not contain the
list of 5GHz rules and thus no wheather radar band rules were inserted by
this code.
But the code didn't fix the n_reg_rules for this regulatory domain and PHY
when this happened. This resulted in a rejection by is_valid_rd because it
found rules which start and end at 0khz. This resulted in a splat like:
Invalid regulatory domain detected

To enable shadow register access, host needs to pass shadow
register configuration to firmware via qmi message. Host also
needs to update ring's HP or TP address to shadow register
address. The write operation to shadow register will be
forwarded to target register by hardware automatically, and
the write operation to shadow register is permitted even
when the target is in power save or sleep mode.
Update the shadow config whenever power up happens.
This feature is controlled by hw parameter supports_shadow_regs which is only

kbuild bot reported than link fails when CONFIG_ATH11K_DEBUGFS is disabled:
drivers/net/wireless/ath/ath11k/dp_rx.c:1662: undefined reference to `ath11k_debugfs_htt_ext_stats_handler'
This was because I had missed to move the static inline version of the function
(which are used when CONFIG_ATH11K_DEBUGFS is disabled) to debufs_htt_stats.h.
Also move ath11k_debugfs_htt_stats_req() at the same time. And create a stub
also for ath11k_debugfs_htt_stats_init() for consistency, even if it's not
needed.

In commit 2d4bcbed5b ("ath11k: initialize wmi config based on hw_params") the
wmi config initialisation was moved to hw_ops->wmi_init_config() but the old
initialisation values were accidentally left to ath11k_wmi_cmd_init(). This
is very confusing, so remove the redundant values.
And this was actually so confusing that in commit aa2092a9ba ("ath11k: add
raw mode and software crypto support") I actually it caused a bug: when
ATH11K_FLAG_RAW_MODE was enabled rx_decap_mode was assigned back to
TARGET_DECAP_MODE_NATIVE_WIFI in ath11k_init_wmi_config_ipq8074(). Fix this at
the same time.
Compile tested only.

Some of the function declarations are for functions in debugfs_htt_stats.c and
debugfs_sta.c, move them to corresponding header files. As debugfs_sta.h didn't
exist create it.
Also in debugfs_htt_stats.h move dunction declarations to the end of the file.
No functional changes. Compile tested only.
