New LLCP will process the CIS establishement in the TX path, meaning it
will only process once every ACL connection interval.
If ACL connection interval is significantly longer than the ISO
interval, CIS packets corresponding to the ACL connection interval will
be lost. This may cause latency in audio rendition.
By processing the CIS establishment in the RX path, notification will be
sent immediately, and audio path is enabled fast to reduce latency.
When a CIS fails to establish, the controller shall complete the
procedure by sending a CIS_ESTABLISHED event containing the error.

PHY update control procedure has to send a notification towards
Host when the PHY is actually changed, when the instant happens.
Control procedures are handled in a prepare phase of a connection
event, hence notifications are send towards host to early.
The fix for that is to postpone send of a notification.
New state has been introduced to remote requested PHY update
control procedure: RP_PU_STATE_WAIT_INSTANT_ON_AIR.
Also new event has been introduced: RP_PU_EVT_NTF, that is used
to inform the PHY update state machine that notification may
be send.
There are two places where the notification events may be generated
ull_conn_rx, just before first received PDU is send towards Host
or ull_conn_done, in case there were no PDU received.

In case there are pending two control procedures: local and remote,
and remote device sends LL_REJECT_IND PDU then assertion happened.
ull_cp_rx function triggers assertion because LL_REJECT_IND is
considered as expected packet for all local and remote control
procedures.
That is not correct. It does not allow local procedure to handle
a response and stops a device on assert.
A remote device should not send LL_REJECT_IND PDU for locally initiated
control procedures, hence local device should not expect to receive
LL_REJECT_IND PDU to be expected one for pending remote control
procedure.
Remote device is allowed to send LL_REJECT_EXT_IND PDU for a locally
initiated control procedures. The LL_REJECT_EXT_IND PDU has a Reject-
Opcode that identifies rejected control procedure, hence is may be
expected by local device.
The commit provides changes that prevent the Controller assertion

The periodic CTE_REQ disable command, requested by Host, may be locked
until connection is dropped due to missing CTE_RSP from peer device.
That is caused by implementation of CTE_REQ disable and CTE_REQ
control procedure handling.
The procedure is marked as active when CTE request was send to peer
device. It is marked as inactive after completion of the procedure.
That caused locking of CTE disable on a semaphore.
The BT 5.3 Core Spec, Vol 4, Part E, section 7.8.85 says the HCI_LE_-
Connection_CTE_Request_Enable should be considered active on a conne-
ction from when Host successfully issues the command with Enable=0x1
until a command is issued with Enable=0x0 or single LLCP CTE request
has finished (CTE_Request_Interval=0x0). Also there is a clarification
from BT SIG that the command with Enable=0x0 does not affect any
initiated LLCP CTE request. That means Controller is allowed to finish
already started procedure and it is not allowed to start new LLCP CTE
request procedure after completion of the command with Enable=0x0.
Taking that into account, there is no need to synchronize ULL and LLL
in regard of disable the LLCP CTE request while the procedure is
pending. Controller is free to complete the procedure or terminate it.
The change removes all code related with cte_req.is_active, disable
callback and waiting of ULL for LLL to finish the LLCP CTE request.
The ULL will complete the HCI_LE_Connection_Request_Enable with
Enable=0x0 immediately. In case the procedure is disabled in before
the response arrives, then further processing of the response is
dropped and the procedure context released.
The context is not released by the code responsible for disable
handling, to have single place where it is done.
