This is a step toward eliminating the RT_TRACE macros. Those calls that
have DBG_EMERG as the level are always logged, and they represent error

This macro can be replaced with WARN_ONCE. In addition to using a
standard debugging macro for these critical errors, we also get
a stack dump.
In rtl8821ae/hw.c, a senseless comment was removed, and an incorrect
indentation was fixed.
This patch also fixes two places in each of rtl8192ee, rtl8723be,
and rtl8821ae where the logical condition was incorrect.

These drivers need to be able to reference "struct ieee80211_hw" from
the driver's private data, and vice versa. The USB driver failed to
store the address of ieee80211_hw in the private data. Although this
bug has been present for a long time, it was not exposed until
commit ba9f93f82aba ("rtlwifi: Fix enter/exit power_save").

We need to perform different actions (AGC and VCO calibrations and VGC
tuning) periodically at different intervals. We don't need separate
works for those, we can use link tuner work and just check for proper
interval on it.
This fixes performing AGC and VCO calibration when scanning on STA
mode. We need to be on-channel to perform those calibrations.

MAX_LEN_CFG_MAX_PSDU specify maximum transmitted by HW AMPDU length
(0 - 8kB, 1 - 16kB, 2 - 32kB, 3 - 64kB). Set this option according to
remote stations capabilities (based on HT ampdu_factor). However limit
the value based our hardware TX capabilities as some chips can not send
more than 16kB (factor 1). Limit for all chips is currently 32kB
(factor 2), but perhaps for some chips this could be increased
to 64kB by setting drv_data->max_psdu to 3.
Since MAX_LEN_CFG_MAX_PSDU is global setting, on multi stations modes
(AP, IBSS, mesh) we limit according to less capable remote STA. We can
not set bigger value to speed up communication with some stations and
do not break communication with slow stations.

There's no need for this to be only __read_mostly, since
it's only written in a single way depending on the module
parameter, so that can be moved into the module's __init
function, and the ops can be __ro_after_init.
This is a little bit safer since it means the ops can't
be overwritten (accidentally or otherwise), which would
otherwise cause an arbitrary function or bad pointer to
be called.

The txpower is being recalculated when adding interface to make sure
txpower won't overshoot the spec, and when removing the interface,
the txpower should again to be recalculated to restore the correct value
from the active interface list.
Following is one of the scenario
vdev0 is created as STA and connected: txpower:23
vdev1 is created as P2P_DEVICE for control interface: txpower:0
vdev2 is created as p2p go/gc interface: txpower is 21
So the vdev2@txpower:21 will be set to firmware when vdev2 is created.
When we tear down the vdev2, the txpower needs to be recalculated to
re-set it to vdev0@txpower:23 as vdev0/vdev1 are the active interface.
ath10k_pci mac vdev 0 peer create 8c:fd:f0:01:62:98
ath10k_pci mac vdev_id 0 txpower 23

Whenever firmware crashes, and both CONFIG_ATH10K_DEBUGFS and
CONFIG_ALLOW_DEV_COREDUMP are enabled, dump information about the crash via a
devcoredump device. Dump can be read from userspace for further analysis from:
/sys/class/devcoredump/devcd*/data
As until now we have provided the firmware crash dump file via fw_crash_dump
debugfs keep it still available but deprecate and a warning print that the user
should switch to using dev_coredump.
Future improvement would be not to depend on CONFIG_ATH10K_DEBUGFS, as there
might be systems which want to get the firmware crash dump but not enable
debugfs. How to handle memory consumption is also something which needs to be
taken into account.

Ath10k reports the phy capability that supports P2P_DEVICE interface.
When we use the P2P supported wpa_supplicant to start connection, it'll
create two interfaces, one is wlan0 (vdev_id=0) and one is P2P_DEVICE
p2p-dev-wlan0 which is for p2p control channel (vdev_id=1).
ath10k_pci mac vdev create 0 (add interface) type 2 subtype 0
ath10k_add_interface: vdev_id: 0, txpower: 0, bss_power: 0
...
ath10k_pci mac vdev create 1 (add interface) type 2 subtype 1
ath10k_add_interface: vdev_id: 1, txpower: 0, bss_power: 0
And the txpower in per vif bss_conf will only be set to valid tx power when
the interface is assigned with channel_ctx.
But this P2P_DEVICE interface will never be used for any connection, so
that the uninitialized bss_conf.txpower=0 is assinged to the
arvif->txpower when interface created.
Since the txpower configuration is firmware per physical interface.
So the smallest txpower of all vifs will be the one limit the tx power
of the physical device, that causing the low txpower issue on other
active interfaces.
wlan0: Limiting TX power to 21 (24 - 3) dBm
ath10k_pci mac vdev_id 0 txpower 21
ath10k_mac_txpower_recalc: vdev_id: 1, txpower: 0
ath10k_mac_txpower_recalc: vdev_id: 0, txpower: 21
ath10k_pci mac txpower 0
This issue only happens when we use the wpa_supplicant that supports
P2P or if we use the iw tool to create the control P2P_DEVICE interface.

The cts protection vdev parameter, in new QCA9377 TF2.0 firmware,
requires bss peer to be created for the STATION vdev type.
bss peer is being allocated by the firmware after vdev_start/_up commands.
