1a2780e0f3 wil6210: temperature measurement
Firmware got support for temperature measurement.
There are 2 temperature sensors: MAC and radio

"not available" temperature - reported by FW as 0 or ~0

b80231773a wil6210: sync with new firmware
Adjust driver for changes in the FW API.
Noticeable changes in the FW are:
- temperature sensing
- infrastructure for multiple connections
- infrastructure for P2P
- signal strength indication

This commit introduces only changes that are required to support same functionality
as previous firmware, no new features.

55f7acdd24 wil6210: new SW reset
New firmware allows for shorter SW reset procedure.
After SW reset, FW raises "fw done" IRQ, at this
moment mailbox control structures are initialized, driver caches it.

New status bit wil_status_reset_done introduced to track completion
of the reset. It is set by "fw ready" irq, and required for WMI rx flow
to access control structures.

WMI Tx flow protected by other status bit, wil_status_fwready. It can't
be set before wil_status_reset_done is set by design.

Although neither version handles negative values particularly well,
the lone caller clamps all negative values to zero anyway.  I have
verified that the results are the same for the range of possible
positive rssi values.

5f34608fa2 carl9170: fix frame drop and WARN due to minstrel_ht change
With "mac80211/minstrel_ht: add support for using CCK rates"
minstrel_ht selects legacy CCK rates as viable rates for
outgoing frames which might be sent as part of an A-MPDU
[IEEE80211_TX_CTL_AMPDU is set].

This behavior triggered the following WARN_ON in the driver:
> WARNING: at carl9170/tx.c:995 carl9170_op_tx+0x1dd/0x6fd
The driver assumed that the rate control algorithm made a
mistake and dropped the frame.

This patch removes the noisy warning altogether and allows
said A-MPDU frames with CCK sample and/or fallback rates to
be transmitted seamlessly.

77ee7c891a cfg80211: comprehensively check station changes
The station change API isn't being checked properly before
drivers are called, and as a result it is difficult to see
what should be allowed and what not.

In order to comprehensively check the API parameters parse
everything first, and then have the driver call a function
(cfg80211_check_station_change()) with the additionally
information about the kind of station that is being changed;
this allows the function to make better decisions than the
old code could.

While at it, also add a few checks, particularly in mesh
and clarify the TDLS station lifetime in documentation.

To be able to reduce a few checks, ignore any flag set bits
when the mask isn't set, they shouldn't be applied then.

   - remove CONFIG_EXPERIMENTAL

e1a0c6b3a4 mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40
For VHT, many more bandwidth changes are possible. As a first
step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag
in the HT capabilities and instead introduce a bandwidth field
indicating the currently usable bandwidth to transmit to the
station. Of course, make all drivers use it.

To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get
the station as an argument, rather than the new capabilities,
so it can set up the new bandwidth field.

If the station is a VHT station and VHT bandwidth is in use,
also set the bandwidth accordingly.

Doing this allows us to get rid of the supports_40mhz flag as
the HT capabilities now reflect the true capability instead of
the current setting.

While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not
ignore HT cap overrides when MCS TX isn't supported (not that it
really happens...)

The code can only be used when ATH9k_DEBUGFS is enabled an not when ATH_DEBUG
is activated. Still enabling it would cause build failures.

c672a3abb7 ath9k: Select RELAY for ATH9K_DEBUGFS
The spectral scan support activated through ATH9K_DEBUGFS depends on RELAY for
the kernel->userspace communication. Not activating RELAY causes build
failures.

The RELAY is added as select instead of depend to do it similar like
the only other user of RELAY: BLK_DEV_IO_TRACE
