3.7.3.4 Message error procedure
When receiving a message that is not understood by an element, it shall
ignore the message.
Note: A message can be falsely identified as a valid message, passing
the NetMIC and TransMIC authentication using a known network key and
application key even though that message was sent using different keys.
The decryption of that message using the wrong keys would result in a
message that is not understood by the element. The probability of such a
situation occurring is small but not insignificant.
A message that is not understood includes messages that have one or more
of the following conditions:
• The application opcode is unknown by the receiving element.
• The access message size for the application opcode is incorrect.
• The application parameters contain values that are currently
Prohibited.
Note: An element that sends an acknowledged message that is not
understood by a peer node will not receive any response message.

This enables chaining ota for periodic advertising. AUX_CHAIN_IND PDUs
will be sent automatically if AuxPtr is detected in preceding PDU.
AuxPtr offset is always set to achieve minimal required frame spacing,
i.e. 300us (T_mafs). AuxPtr in all PDUs in advertising train are
updated on enqueue since PDU spacing is already known at that time so
we do not need to waste time in LLL.
Signed-off-by: Andrzej Kaczmarek <andrzej.kaczmarek@codecoup.pl>
This adds support to allow advertising PDUs to be linked which is
required to send advertising trains, i.e. AUX_CHAIN_IND.
PDUs are linked with a simple single-linked list, the pointer to next
PDU is stored at the very end of PDU buffer. This prevents it from
being overwritten if PDU is modified and allows for build time offset
calculation.
There are few helpers added to make handling easier, e.g.:
- get next linked PDU
- get last linked PDU
- link one PDU to another
- link PDU at the end
- release all linked PDUs (except for 1st)

We previously removed the iso data path when the iso channel
disconnected. Since the iso data path is unique for a given
iso channel (by handle), it does not make sense to remove
it for a disconnected channel, as the channel is, in
a sense, not existing anymore.
This update is to better comply with the bluetooth
core spec, and to avoid getting errors from the
controller on disconnect.
Rather than removing the implementation of being able
to remove the data path, the function was made non-static
and moved to the internal header file, in case we ever
want to use it. This should not affect compile size.

Move the function from scan.c to hci_core.c.
When in scan.c, the function is only available if
CONFIG_BT_OBSERVER was enabled. Since the function
can be used in other scenarioes where we need to parse
LTV data, it has been moved to a more generic place.
hci_core.c might not be the ideal place, but it is
where most other common bluetooth functions
are located.

After #35702, the provisioner is unable to mark a link as closed, as
it depends on the send_end callback to be called, so it can start its
timer. PB-Adv keeps a reference to the buffers of reliable messages,
which prevents this callback to be invoked, as the buffer destructor is
never called.

replace the timer based LINK_CLOSE message tx duration with a message
