- API
- collision handling
- invalid PDUs
- unsupported procedures
- buffer allocation
- TX queue

- PHY update
- Encryption
- Ping
- Version
- Channel map update
- Min. used channels

f0c610ce0d bluetooth: controller: update unittests for improved ZTEST framework
Update the unittests for feature exchange to use the new ZTEST API
Here we only update the feature exchange procedure. The remaining
unittests will be done in a next PR

Mocks, helper routines and the Unit Under Test are splitted out as
a library instead of adding them to the file list

131c089aaf Bluetooth: Controller: llcp: Fix wrong eff time calc if PHY changed
If there is a PHY change on a connection it may happen that effective
RX and TX time changes also. That change is applied after an instant.

Implemented handling of effective time calculation is based on the
maximum PDU length, new PHY and local (default) maximum TX or RX time.

The maximum TX value is set to default one that corresponds to PHY 1M
during the Controller initialization. It can be updated by host to other
value. By default Zephyr Host updates it to max possible TX time for all
supported PHYs. If PHY CODED is enabled, it is the longest possible TX
duration 17040 us.

The maximum RX value is set to default during connection creation.
In case of use of legacy advertising, the value is also related with
PHY 1M. It can be updated by data length extension procedure.

If the maximum RX value is set to some value and there is a change
of a PHY to one that requires more time to send a PDU with the same
length, then the maximum RX value is wrongly calculated.

Function pu_calc_eff_time returns a value that is the default_time
argument. The problem is that the default_time should be adjusted
to new maximum RX time required for a new PHY.

To solve that there should be an evaluation of a new maximum RX and
TX time based on new PHY.

The commit adds missing evaluation.

The problem occurred in DF tests that check collision mitigation
between PHY update control procedure and CTE request control procedure.

There was missing CONFIG_BT_CTLR_PHY_CODED option in CTE request
unit tests. The code was working because the ULL implementation of
PHY change control procedure does not verify if PHY CODED is supported.

When missing support was enabled, tests showed wrong evaluation of
maximum RX time. It also unveiled error in CTE request unit tests
implementation. The default_tx_time was set to wrong value 2120 us
as if PHY CODED was not supported. To fix it, the value was changed
to PDU_DC_PAYLOAD_TIME_MAX_CODED.

There was also added a mock for a feature exchange procedure done
during unit tests setup step. That allows to correctly calculate
maximum TX time by ull_dle_max_time_get function.

4d3985f93c Bluetooth: Controller: Enable PDU CP bit when CTE RX is enabled
The CP bit is read in DF connected mode while interpreting
LL_CTE_RSP PDU, hence it must be available in struct pdu_data
type.

There were missing two Kconfig options in new LLCP tests.
They were reponsbile for disable of CP bit instruct pdu_data.
That caused tests to fail during compilation.

f023b5f611 Bluetooth: controller: push topic branch to main
Pushes all work done in the topic-ble-llcp branch into main branch
This is a refactoring of the LL control procedures; the refactored
control procedures are hidden behind a KConfig option and
per default disabled

Goal of the refactoring:

close issue Link Layer Control Procedure overhaul #15256
make it easier to add/update control procedures
Refactoring consists in principal of writing explicit state machines
for the control procedures.
To reduce the risk of regression errors unit-tests have been added

Following control procedures are implemented:

Connection update procedure
Channel map update procedure
Encryption procedure
Feature exchange procedure
Version exchange procedure
ACL termination procedure
Connection parameters request procedure
LE Ping procedure
Data Length Update procedure
PHY update procedure
Min. nr. Of channels used procedure
Constant Tone extension request procedure

This is a joined work by the people listed in the signed-off-by
list (in alphabetical order)
