8196770737 drivers: ieee802154: propagate frame counter to upper layer
When frame counter is managed by the radio driver the upper layer
needs to be informed about the frame counter changed. The upper layer
looks for the most recent frame counter in the transmitted frame,
this is why the tx_payload need to be updated after processed by
the radio driver.

cab64a9c61 drivers: ieee802154: copy back the TX buffer into the upper layer
Copy back the TX buffer content back into the upper layer
in case of a TX failure.

This is necessary in when frame encryption by the radio driver
is used. The shim layer for the nRF5 driver has a buffer, that
is used by the driver to authenticate and encrypt the frame
in-place. In case of a TX failure, the buffer contents
are propagated back to the upper layer. The upper layer
must use the same secured frame for retransmission.

b10428163a kernel: sem: add K_SEM_MAX_LIMIT
Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".

Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.

In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.

These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.

a42d6c98d3 drivers: ieee802154_nrf5: Block on net_pkt allocation in the RX path
Currently, if no net_pkt's are available, the radio driver RX thread
drops the 802.15.4 frame silently. This causes undesired behaviour,
where we can drop the packet which has already been acknowledged at
the 802.15.4 level.

Fix this, by blocking the RX thread if no net_pkt is avaliable. The
packets received while the RX thread is blocked will be accumulated in
the underlying nRF 802.15.4 driver, and eventually when it runs out of
internal buffers before the thread is unblocked, it'll stop
acknowledging the incoming frames.

949b25cf68 drivers: ieee802154: Fix device instance const qualifier loss
In all of these drivers, passing the device's data was sufficient as
only the data is being used by thread.

e18fcbba5a device: Const-ify all device driver instance pointers
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *
