In iwl_mvm_tx_skb_non_sta(), in case of managed interface,
the AP station was supposed to be used for multicast frames
instead of the auxiliary station to avoid frames possibly
sent to an absent P2P GO. However, when moving to DQA mode,
this was broken as no valid queue was assigned. This is fixed
by a recent patch that directs all non-offchannel traffic to
ap station earlier in the TX path. However, the broken, and
now dead code, remained. Remove it.

When building AMSDU for gen2, code uses iwl_tx_cmd. The only
updated field is len, which is in the same location, so it
is not a bug. However, it is a bit confusing and error prone,
so change it.

The function cw1200_bss_info_changed() and cw1200_hw_scan() can be
concurrently executed.
The two functions both access a possible shared variable "frame.skb".
This shared variable is freed by dev_kfree_skb() in cw1200_upload_beacon(),
which is called by cw1200_bss_info_changed(). The free operation is
protected by a mutex lock "priv->conf_mutex" in cw1200_bss_info_changed().
In cw1200_hw_scan(), this shared variable is accessed without the
protection of the mutex lock "priv->conf_mutex".
Thus, concurrency use-after-free bugs may occur.
To fix these bugs, the original calls to mutex_lock(&priv->conf_mutex) and
mutex_unlock(&priv->conf_mutex) are moved to the places, which can
protect the accesses to the shared variable.

When the update_connect_param callback is set, nl80211 expects the flag
WIPHY_FLAG_SUPPORTS_FW_ROAM to be set as well. However, this flag is
only set when modparam roamoff=0, while the callback is set
unconditionally. Since commit 7f9a3e150ec7 this causes a warning in
wiphy_register, which breaks brcmfmac.
Disable the update_connect_param callback when roamoff=0 to fix this.

HL2.0 firmware does not support setting quiet mode. If the host driver sends
the quiet mode setting command to the HL2.0 firmware, it crashes with the below
signature.
fatal error received: err_qdi.c:456:EX:wlan_process:1:WLAN RT:207a:PC=b001b4f0
The quiet mode command support is exposed by the firmware via thermal throttle
wmi service. Enable ath10k thermal support if thermal throttle wmi service bit
is set. 10.x firmware versions support this feature by default, but
unfortunately do not advertise the support via service flags, hence have to
manually set the service flag in ath10k_core_compat_services().
Tested on QCA988X with 10.2.4.70.9-2. Also tested on WCN3990.

Move getting the phy_data out one layer up and the info type into

The firmware changed the PHY data API, so follow suit.
Some data is now available even for HT/VHT frames, so
the info type in the metadata was changed. This change
isn't backwards compatible, but
1) the firmware with the old API was never released;
2) the only overlap in the info type field is from the
old type of TB to the new of HT, so this basically
just means that with older FW and newer driver the
data will be considered missing.
While at it, remove the extra code to set the LTF syms
corresponding to the streams and use the data from the
device instead - we don't really need this in any case
other than when we have it from the device.
As the new API gives use the spatial reuse 1-4 fields
for trigger-based PPDUs, also expose that to radiotap.

When removing the driver, the following flow can happen:
1. host command is in progress, for example at index 68.
2. RX interrupt is received with the response.
3. Before it is processed, the remove flow kicks in, and
calls iwl_pcie_txq_unmap. The function cleans all DMA,
and promotes the read pointer to 69.
4. RX thread proceeds with the processing, and is calling
iwl_pcie_cmdq_reclaim, which will print this error:
iwl_pcie_cmdq_reclaim: Read index for DMA queue txq id (0),
index 4 is out of range [0-256] 69 69.
Detect this situation, and avoid the print. Change it to
warning while at it, to make such issues more noticeable
in the future.

When traffic load is not low or low latency is active, TCM schedules
re-evaluation work so in case traffic stops TCM will detect that
traffic load has become low or that low latency is no longer active.
However, if TCM is paused when the re-evaluation work runs, it does
not re-evaluate and the re-evaluation work is no longer scheduled.
As a result, TCM will not indicate that low latency is no longer
active or that traffic load is low when traffic stops.
Fix this by forcing TCM re-evaluation when TCM is resumed in case
low latency is active or traffic load is not low.

This function is only half-used by mvm (i.e. only the nvm_version part
matters, since the calibration version is irrelevant), so it's
pointless to export it from iwlwifi. If mvm uses this function, it
has the additional complexity of setting the calib version to a bogus
value on all cfg structs.
To avoid this, move the function to dvm and make a simple comparison
of the nvm_version in mvm instead.

Comparing the existing TX_BITRATE parsing code (in
mwifiex_parse_htinfo()) with the RX bitrate histograms in debugfs.c, it
appears that the rxpd_rate and rxpd_htinfo fields have the same format.
At least, they give reasonable results when I parse them this way.
So this patch adds support for RX_BITRATE to our station info dump.
Along the way, I add legacy bitrate parsing into the same function,
using the debugfs code (mwifiex_histogram_read() and
mwifiex_adjust_data_rate()) as reference.
Additionally, to satisfy the requirements of
NL80211_STA_INFO_RX_BITRATE, I skip logging the bitrate of multicast
packets. This shouldn't add a lot of overhead to the RX path, as there
are already several similar 802.3 header checks in this same codepath.
We can also bias the branch behavior to favor unicast, as that's the
common performance-sensitive case.
I'd consider this support somewhat experimental, as I have zero
documentation from Marvell. But the existing driver code gives me good
reason to think this is correct.
I've tested this on a few different 802.11{a,b,g,n,ac} networks, and the
reported bitrates look good to me.

the following hw flags:
- IEEE80211_HW_STA_MMPDU_TXQ
- IEEE80211_HW_BUFF_MMPDU_TXQ
This can produce a NULL pointer dereference in mt76_stop_tx_queues
since mt76 iterates on all available sta tx queues assuming they are

(it has not triggered any crash yet)

This reverts commit 5188d5453bc9380ccd4ae1086138dd485d13aef2, because it
introduced lock recursion:
BUG: spinlock recursion on CPU#2, kworker/u13:1/395
lock: 0xffffffc0e28a47f0, .magic: dead4ead, .owner: kworker/u13:1/395, .owner_cpu: 2
CPU: 2 PID: 395 Comm: kworker/u13:1 Not tainted 4.20.0-rc4+ #2
Hardware name: Google Kevin (DT)

This was clearly not tested well at all. I simply performed 'wget' in a
loop and it fell over within a few seconds.

With commit 0a9f8f0a1ba9 ("rtlwifi: fix btmpinfo timeout while processing
C2H_BT_INFO"), calling rtl_c2hcmd_enqueue() with rtl_c2h_fast_cmd() true,
the routine returns without freeing that skb, thereby leaking it.
This issue has been discussed at https://github.com/lwfinger/rtlwifi_new/issues/401
and the fix tested there.
