Both BT_CONNECTED and BT_CONFIG state mean that we have a baseband link
available. We should therefore check for either of these when pairing

The HCI_CONN_LE_SMP_PEND flag is supposed to indicate whether we have an
SMP context or not. If the context creation fails, or some other error
is indicated between setting the flag and creating the context the flag
must be cleared first.

This patch ensures that smp_chan_create() clears the flag in case of
allocation failure as well as reorders code in smp_cmd_security_req()
that could lead to returning an error between setting the flag and
creating the context.

Without the patch the following kind of kernel crash could be observed
(this one because of unacceptable authentication requirements in a

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.

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.

In case of A-MSDU RX we should check attention flags
correctly to be sure we report correct FCS status for
A-MSDU subframes. Without a patch we could report A-MSDU
subframes with wrong FCS as a correct to the stack, next
get a lot of DUP ACK TCP packets. Finally TP drop is seen
and this drop depends on FCS errors ratio for A-MSDU frame.

Example test case when TP drop is seen:
- ath10k configured as an AP
- used ath10k station
- forced A-MSDU (7 frames) on STA
- other traffic on channel (often FCS errors)
- monitor iface added on AP
- TCP STA -> AP traffic (iperf)

The 10.x firmware does not support IBSS mode at
all. It can't beacon and it crashes when trying to
scan.

Firmware doesn't perform Rx reordering so it is
left to the host driver to do that.

Use mac80211 to perform reordering instead of
re-inventing the wheel.

This fixes TCP throughput issues in some
environments.

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.
