When a station is removed, its statistics may be interesting to
userspace, for example for further aggregation of statistics of
all stations that ever connected to an AP.
Introduce a new cfg80211_del_sta_sinfo() function (and make the
cfg80211_del_sta() a static inline calling it) to allow passing
a struct station_info along with this, and send the data in the
nl80211 event message.

Add the time spent scanning to the survey data so it can be

Not all devices are able to report survey data (particularly
time spent for various operations) per channel. As all these
statistics already exist in survey data, allow such devices
to report them (if userspace requested it)

All of the survey data is (currently) per channel anyway,
so having the word "channel" in the name does nothing. In
the next patch I'll introduce global data to the survey,
where the word "channel" is actually confusing.

When hw acceleration is enabled, the GENERATE_IV or PUT_IV_SPACE flags
only require headroom space. Therefore, the tailroom-needed counter can
safely be decremented for most drivers.
The older incarnation of this patch (ca34e3b5) assumed that the above
holds true for all drivers. As reported by Christopher Chavez and
researched by Christian Lamparter and Larry Finger, this isn't a valid
assumption for p54 and cw1200.
Drivers that still require tailroom for ICV/MIC even when HW encryption
is enabled can use IEEE80211_KEY_FLAG_RESERVE_TAILROOM to indicate it.

This reverts commit ca34e3b5c808385b175650605faa29e71e91991b.
It turns out that the p54 and cw2100 drivers assume that there's
tailroom even when they don't say they really need it. However,
there's currently no way for them to explicitly say they do need
it, so for now revert this.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=90331.

A new TLV supplies the ADMA address for SDIO mode, allowing

use until the FW sends the ALIVE message.
Use the value given by the FW in the IWL_UCODE_TLV_SDIO_ADMA_ADDR

the ALIVE message. If it isn't given in the FW - use the current
hardcoded values.

In case the rate mask for one of the modulations was zero the
max rate idx for that modulation was set to 32 (BITS_PER_LONG).
This is bad as it would later lead to an out of bounds access
to the expected tpt table. In most cases there was no real effect
as the expected tpt was set to 0 and this led to avoiding the
modulation effectively.
Fix the out of bounds access and explicitly skip the modulation
in case there's no rate allowed in it.

The allocation of the DCCM between the data and the stack
can theoretically change without notice to the driver, but
the total size is HW-fixed. Since the stack CCM (runtime
stack) has also data important to the FW - this patch allows
pulling the whole DCCM in one piece and adds it to the dump
data.
If the size isn't known - just use the data part of the
DCCM as it appears in the FW TLVs.
