Bluetooth: Fix white list handling with resolvable private addresses
Devices using resolvable private addresses are required to provide
an identity resolving key. These devices can not be found using
the current controller white list support. This means if the kernel
knows about any devices with an identity resolving key, the white
list filtering must be disabled.
However so far the kernel kept identity resolving keys around even
for devices that are not using resolvable private addresses. The
notification to userspace clearly hints to not store the key and
so it is best to just remove the key from the kernel as well at
that point.
With this it easy now to detect when using the white list is
possible or when kernel side resolving of addresses is required.

Bluetooth: Add support for using controller white list filtering
The Bluetooth controller can use a white list filter when scanning
to avoid waking up the host for devices that are of no interest.
Devices marked as reporting, direct connection (incoming) or general
connection are now added to the controller white list. The update of
the white list happens just before enabling passive scanning.
In case the white list is full and can not hold all devices, the
white list is not used and the filter policy set to accept all
advertisements.
Using the white list for scanning allows for power saving with
controllers that do not handle the duplicate filtering correctly.

Bluetooth: Fix issue with ADV_IND reports and auto-connection handling
When adding remote devices to the kernel using the Add Device management
command, these devices are explicitly allowed to connect. This kind of
incoming connections are possible even when the controller itself is
not connectable.
For BR/EDR this distinction is pretty simple since there is only one
type of incoming connections. With LE this is not that simple anymore
since there are ADV_IND and ADV_DIRECT_IND advertising events.
The ADV_DIRECT_IND advertising events are send for incoming (slave
initiated) connections only. And this is the only thing the kernel
should allow when adding devices using action 0x01. This meaning
of incoming connections is coming from BR/EDR and needs to be
mapped to LE the same way.
Supporting the auto-connection of devices using ADV_IND advertising
events is an important feature as well. However it does not map to
incoming connections. So introduce a new action 0x02 that allows
the kernel to connect to devices using ADV_DIRECT_IND and in addition
ADV_IND advertising reports.
This difference is represented by the new HCI_AUTO_CONN_DIRECT value
for only connecting to ADV_DIRECT_IND. For connection to ADV_IND and
ADV_DIRECT_IND the old value HCI_AUTO_CONN_ALWAYS is used.

iwlwifi: mvm: add Aux ROC request/response flow
The Remain On Channel framework added to the firmare is
a bit like time events. It allows the driver to request
the firmware to be on a certain channel for a certain time.
Unlike the time events, the ROC infrastructure doesn't need
a MAC context in the firmware - it uses a generic context
called "auxiliary framework".
This is useful for any offchannel activity that is not bound
to a specific MAC.
The flow is synchronized much like with time events:
1) The driver receives an action frame from the wpa_supplicant
via nl80211 that requests to be sent offchannel.
2) The driver sends an Aux ROC command (0x53) to the firmware.
3) The firmware responds with the unique id of the time event.
4) When time event starts, the driver puts the frame in the
Aux queue.
Special care needs to be taken when the time events ends:
the queue needs to be cleaned-up.

cfg80211: fix TDLS setup with VHT peers
Some VHT TDLS peers (Google Nexus 5) include the VHT-AID IE in their
TDLS setup request/response. Usermode passes this aid as the station
aid, causing it to fail verifiction, since this happens in the
"set_station" stage. Make an exception for the TDLS use-case.

The only case where userspace will need to pass the initiator is when the

it won't be a problem in practice.
