The RTL8822BE is a new Realtek wifi and BT device. Support for the BT
part is hereby added.
As this device is similar to most of the other Realtek BT devices, the
changes are minimal. The main difference is that the 8822BE needs a
configuration file for enabling and disabling features. Thus code is
added to select and load this configuration file. Although not needed
at the moment, hooks are added for the other devices that might need
such configuration files.
One additional change is to the routine that tests that the project
ID contained in the firmware matches the hardware. As the project IDs
are not sequential, continuing to use the position in the array as the
expected value of the ID would require adding extra unused entries in
the table, and any subsequant rearrangment of the array would break the
code. To fix these problems, the array elements now contain both the
hardware ID and the expected value for the project ID.

Here is a set of patches that add some more tracepoints and improve a couple
of existing ones. New additions include:
(1) Connection refcount tracking.
(2) Client connection state machine tracking.
(3) Tx and Rx packet lifecycle.
(4) ACK reception and transmission.
(5) recvmsg processing.
Updates include:
(1) Print the symbolic packet name in the Rx packet tracepoint.
(2) Additional call refcount trace events.
(3) Improvements to sk_buff tracking with AF_RXRPC.
In addition:
(1) Config option to inject packet loss during both transmission and
reception.
(2) Removal of some printks.
This series needs to be applied on top of the previously posted fixes.
