The condition boot_iteration == HDA_FW_BOOT_ATTEMPTS to determine
the log level for the DSP status dump would only work in the case of DSP
init failure after maximum number of attempts to initialize the DSP. If
DSP init succeeds in less than HDA_FW_BOOT_ATTEMPTS attempts and FW
loading fails, the ROM status dump would end up getting logged as debug
instead of an error.
So, add a new flag, SOF_DBG_DUMP_LOG_ERROR, to explicitly specify
the log level for DSP status dump.

The actual code is silently ignoring a thermal zone update when a
driver is requesting it without a get_temp ops set.
That looks not correct, as the caller should not have called this
function if the thermal zone is unable to read the temperature.
That makes the code less robust as the check won't detect the driver
is inconsistently using the thermal API and that does not help to
improve the framework as these circumvolutions hide the problem at the
source.
In order to detect the situation when it happens, let's add a warning
when the update is requested without the get_temp() ops set.
Any warning emitted will have to be fixed at the source of the
problem: the caller must not call thermal_zone_device_update if there
is not get_temp callback set.

NL80211_CMD_SET_SAR_SPECS is added to configure SAR from
user space. NL80211_ATTR_SAR_SPEC is used to pass the SAR
power specification when used with NL80211_CMD_SET_SAR_SPECS.
Wireless driver needs to register SAR type, supported frequency
ranges to wiphy, so user space can query it. The index in
frequency range is used to specify which sub band the power
limitation applies to. The SAR type is for compatibility, so later
other SAR mechanism can be implemented without breaking the user
space SAR applications.
Normal process is user space queries the SAR capability, and
gets the index of supported frequency ranges and associates the
power limitation with this index and sends to kernel.

I hit a bug in which we started a CSA with an action frame,
but the AP changed its mind and didn't change the beacon.
The CSA wasn't cancelled and we lost the connection.
The beacons were ignored because they never changed: they
never contained any CSA IE. Because they never changed, the
CRC of the beacon didn't change either which made us ignore
the beacons instead of processing them.
Now what happens is:
1) beacon has CRC X and it is valid. No CSA IE in the beacon
2) as long as beacon's CRC X, don't process their IEs
3) rx action frame with CSA
4) invalidate the beacon's CRC
5) rx beacon, CRC is still X, but now it is invalid
6) process the beacon, detect there is no CSA IE
7) abort CSA

When we set up a TDLS station, we set sta->sta.bandwidth solely based
on the capabilities, because the "what's the current bandwidth" check
is bypassed and only applied for other types of stations.
This leads to the unfortunate scenario that the sta->sta.bandwidth is
160 MHz if both stations support it, but we never actually configure
this bandwidth unless the AP is already using 160 MHz; even for wider
bandwidth support we only go up to 80 MHz (at least right now.)
For iwlwifi, this can also lead to firmware asserts, telling us that
we've configured the TX rates for a higher bandwidth than is actually
available due to the PHY configuration.
For non-TDLS, we check against the interface's requested bandwidth,
but we explicitly skip this check for TDLS to cope with the wider BW
case. Change this to
(a) still limit to the TDLS peer's own chandef, which gets factored
into the overall PHY configuration we request from the driver,
and
(b) limit it to when the TDLS peer is authorized, because it's only
factored into the channel context in this case.
