The patch adds state bits, storage and HCI command chains for sending
and receiving Bluetooth Mesh advertising packets, and delivery to
requesting user space processes. It specifically creates 4 new MGMT
commands and 2 new MGMT events:
MGMT_OP_SET_MESH_RECEIVER - Sets passive scan parameters and a list of
AD Types which will trigger Mesh Packet Received events
MGMT_OP_MESH_READ_FEATURES - Returns information on how many outbound
Mesh packets can be simultaneously queued, and what the currently queued
handles are.
MGMT_OP_MESH_SEND - Command to queue a specific outbound Mesh packet,
with the number of times it should be sent, and the BD Addr to use.
Discrete advertisments are added to the ADV Instance list.
MGMT_OP_MESH_SEND_CANCEL - Command to cancel a prior outbound message
request.
MGMT_EV_MESH_DEVICE_FOUND - Event to deliver entire received Mesh
Advertisement packet, along with timing information.
MGMT_EV_MESH_PACKET_CMPLT - Event to indicate that an outbound packet is
no longer queued for delivery.

BT core driver should addtionally check LMP feature bit
"Erroneous Data Reporting" instead of quirk
HCI_QUIRK_BROKEN_ERR_DATA_REPORTING set by BT device driver to decide if
HCI commands HCI_Read|Write_Default_Erroneous_Data_Reporting are broken.

This feature indicates whether the device is able to support the
Packet_Status_Flag and the HCI commands HCI_Write_Default_-
Erroneous_Data_Reporting and HCI_Read_Default_Erroneous_-
Data_Reporting.
the quirk was introduced by 'commit cde1a8a992 ("Bluetooth: btusb: Fix

commands HCI_Read|Write_Default_Erroneous_Data_Reporting broken by BT
device driver, but the reason why these two HCI commands are broken is
that feature "Erroneous Data Reporting" is not enabled by firmware, this
scenario is illustrated by below log of QCA controllers with USB I/F:

This event is received when the controller stops advertising,
specifically for these three reasons:
(a) Connection is successfully created (success).
(b) Timeout is reached (error).
(c) Number of advertising events is reached (error).
(*) This event is NOT generated when the host stops the advertisement.
Refer to the BT spec ver 5.3 vol 4 part E sec 7.7.65.18. Note that the
section was revised from BT spec ver 5.0 vol 2 part E sec 7.7.65.18
which was ambiguous about (*).
Some chips (e.g. RTL8822CE) send this event when the host stops the
advertisement with status = HCI_ERROR_CANCELLED_BY_HOST (due to (*)
above). This is treated as an error and the advertisement will be
removed and userspace will be informed via MGMT event.
On suspend, we are supposed to temporarily disable advertisements,
and continue advertising on resume. However, due to the behavior
above, the advertisements are removed instead.
This patch returns early if HCI_ERROR_CANCELLED_BY_HOST is received.

Some devices, e.g. the RTL8723BS bluetooth part, some USB attached devices,
completely drop from the bus on a system-suspend. These devices will
have their driver unbound and rebound on resume (when the dropping of
the bus gets detected) and will show up as a new HCI after resume.
These devices do not benefit from the suspend / resume handling work done
by the hci_suspend_notifier. At best this unnecessarily adds some time to
the suspend/resume time. But this may also actually cause problems, if the
code doing the driver unbinding runs after the pm-notifier then the
hci_suspend_notifier code will try to talk to a device which is now in
an uninitialized state.
This commit adds a new HCI_QUIRK_NO_SUSPEND_NOTIFIER quirk which allows
drivers to opt-out of the hci_suspend_notifier when they know beforehand
that their device will be fully re-initialized / reprobed on resume.

For some reason they tend to squat on the very first CSR/
Cambridge Silicon Radio VID/PID instead of paying fees.
This is an extremely common problem; the issue goes as back as 2013
and these devices are only getting more popular, even rebranded by
reputable vendors and sold by retailers everywhere.
So, at this point in time there are hundreds of modern dongles reusing
the ID of what originally was an early Bluetooth 1.1 controller.
Linux is the only place where they don't work due to spotty checks
in our detection code. It only covered a minimum subset.
So what's the big idea? Take advantage of the fact that all CSR
chips report the same internal version as both the LMP sub-version and
HCI revision number. It always matches, couple that with the manufacturer
code, that rarely lies, and we now have a good idea of who is who.
Additionally, by compiling a list of user-reported HCI/lsusb dumps, and
searching around for legit CSR dongles in similar product ranges we can
find what CSR BlueCore firmware supported which Bluetooth versions.
That way we can narrow down ranges of fakes for each of them.
e.g. Real CSR dongles with LMP subversion 0x73 are old enough that
support BT 1.1 only; so it's a dead giveaway when some
third-party BT 4.0 dongle reuses it.
So, to sum things up; there are multiple classes of fake controllers
reusing the same 0A12:0001 VID/PID. This has been broken for a while.
