4fc0bfb0e8 Bluetooth: Controller: df: CP bit not cleared in DF conn mode RX
In direction finding connected mode there is a CP bit that is set
data PDU header. The bit was initialized only if CTE transmission
was enabled. In case of reception of a CTE the bit was available
in PDUs but not initialized.
That caused issues in connection maintenance if PDU memory buffers
were reused. PDU were malformed and connections were lost.

8f444e490c Bluetooth: Controller: Fix missing offset adjust field assignment
Fix missing offset adjust field assignment in the Periodic
Advertising's sync_info struct that is present in the
Extended Advertising PDU.

When the sync offset is equal or over 2.4576 seconds from
the Extended Advertising PDU, then the sync offset has to
be reduced by 2.4576 seconds and the offs_adjust flag be
set in the sync_info field.

This fixes a bug where Periodic Synchronization could not
be established for Periodic Advertisings with intervals
greater than 2.4576 seconds as the sync offset was
incorrect due to rollover in the 13-bit offset field.

aa4819994e Bluetooth: Controller: Add packet TX restrictions for CTE REQ/RSP PDUs
There are packet restrictions imposed by PHY update procedure
for PDU that includes CTE (BT Core 5.3 :
- central/peripheral can't send PDU with CTE after receive or send
LLPHY_UPDATE_IND until instant if the PHY after instant is CODED
- peripheral can't send PDU including CTE after it sends LL_PHY_REQ
PDU until receive LL_PHY_UPDATE_IND, LL_UNKNOWN_RSP, LL_REJECTED_EXT_-
IND_PDU if there is a CODE PHY in TX_PHYS
- peripheral can't send PDU including CTE after it sends LL_PHY_RSP
PDU until receive LL_PHY_UPDATE_IND if there is a CODED PHY in TX_PHYS
of LL_PHY_RSP PDU or RX_PHYS of LL_PHY_REQ PDU.

The BT 5.3 Core spec defines only one PDU that may include CTE, that is
LL_CTE_RSP PDU. To avoid a situation that there is such PDU enqueued
for transmission in LLL when packet transmission restrictions should
be applied, both procedures in almost all cases will not be executed
in parallel.

Current implementation always handles remote procedurerequest first.

There are possible three scenarios:
1. Remotely requested PHY update. Locally initiated CTE REQ.
   In this case there is no problem with LL_CTE_RSP waiting in a TX
   queue in LLL. Both procedures may be executed one after another.
2. Remotely requested CTE REQ. Locally initiated PHY update.
   In this case the CTE REQ is handled first and it will pause the
   PHY update procedure until LL_CTE_RSP PDU is acknowledged by
   remote. Then the CTE REQ procedure will be completed and PHY update
   continued.
3. Locally initiated PHY update is pending. Arrives remote CTE REQ.
   In this case the CTE REQ will be paused until localy initiated PHY
   update is completed. Then the CTE REQ will be continued.

Thanks to that there should be no PDU including CTE in LLL TX quueue.
That releases us from a situation there is a LL_CTE_RSP PDU in the
LLL TX qeueue that must be changed into LL_REJECT_EXT_IND PDU due to
change of PHY to CODED PHY after PHY update procedure completes.

bb8a2da1fe Bluetooth: Controller: llcp: Fix PHY update FSM stale after instant
In peripheral role when:
 - data length update is enabled
 - the CONFIG_BT_MAX_CONN is set to 1
the PHY update control procedure after reaching instant sends two
notifications to host. It notifies host about PHY update and data
length change. Both notifications are send one after another, so two
free node rx are required. The number of available node rx in
provided conditions is one. The PHY update FSM is stalled in waiting
state for enough empty node rx. At the same time remote device is
allowed to send new remote control procedures. Received request are
handled by PHY update FSM that asserts due to unknown procedure opcode.

The commit changes number of allocated nodes to be two times a number
of LLCP connections.

This is a workaround for the issue. The best solution seems to be
sharing nodsx between connections. Though this solution requires
buffering remote control procedures until host notification is done.

30ebda34cf Bluetooth: Controller: radio: Fix error in pkt conf macros
Macros responsible for preparation of packet configuration flags in
regard of PHY and CTE were wrong. PHY flags are not used as regular
integer values but bits in a bitfield, hence size of the field in
packet configuration flags is three instead of two.
In such case CTE presen filed should be moved to bit 4th.

The problem was spot when testing implementation with CODED PHY
enabled. When device was sending PDUs that had attached CTE the
radio was configured to use CODED PHY due to wrong bit set in
packet configuration flags variable (overlapping of CTE bit
with CODED PHY bit).
