Add assert check to detect failure to enqueue ticker
operations. This will avoid HCI thread from stalling
forever on k_sem_take.
This assert will trigger on design fault, not defining
enough queued ticker operations count.

Added a missing NULL pointer dereference check and made the
structure member scan->per_scan.sync and timeout_reload as
volatile, as they are modified in ISR context.

Added link structure allocation explanation related to HCI
event generation by the controller.

Fix the auxiliary pointer and sync information offset and
offset unit population. Offsets are 13-bit value, use 300 us
offset unit when offset value using 30 us offset unit does
not fit in 13-bits.

Add the missing resources like ticker instances, Rx PDU
buffers and memory queue link buffers, that are required
for Periodic Advertising Sync creation.

Remove the redundant ticker update check, ticker is not
stopped and started in Periodic Advertising unlike in a
Connection Update Procedure in connections.

Fix uninitialized rl_idx value for the Extended Advertising
PDU received in the auxiliary channels. This caused
uninitialized rl_idx to be used by HCI layer and fail an
assert check in ull_filter.c file.

Fix missing periodic advertising start due to missing
allocation of auxiliary context when no Extended
Advertising PDU on auxiliary channels.

Remove conditional compilation on structure definition in
pdu.h so as to allow inclusion of header files with
function prototypes that use those structures. I.e. to
avoid conditionally including the header file.

based on incoming Tx buffer throughput.

Add Force MD bit feature wherein connection events can be
extended to match the rate at which applications provide
new Tx data. MD bit in Tx PDUs is forced on if there has
been CONFIG_BT_CTLR_TX_BUFFERS count number times Tx/Rx
happened in a connection event. The assumption here is,
if controller's tx buffers are full, it is probable that
the application would send more Tx data during the
connection event, and keeping the connection event alive
will help improve overall throughput.
