Even though radio driver can report in its capabilities that it does
support CSMA CA, there's no way in the driver to select how the frame
should be transmitted (with CSMA or without). As layers above radio
driver (Thread, Zigbee) can expect that both TX modes are available, we
need to extend the API to allow either of these modes.
This commits extends the API `tx` function with an extra parameter,
`ieee802154_tx_mode`, which informs the driver how the packet should be
transmitted. Currently, the following modes are specified:
* direct (regular tx, no cca, just how it worked so far),
* CCA before transmission,
* CSMA CA before transmission,
* delayed TX,
* delayed TX with CCA
Assume that radios that reported CSMA CA capability transmit in CSMA CA
mode by default, all others will support direct mode.

By changing the various *NET_DEVICE* macros. It is up to the device
drivers to either set a proper PM function or, if not supported or PM
disabled, to use device_pm_control_nop relevantly.
All existing macro calls are updated. Since no PM support was added so
far, device_pm_control_nop is used as the default everywhere.

Upper layers like OpenThread expect the radio driver to forward ACK
frame received by the radio.
Simulate this behavior on kw41z by recreating the ACK frame from the
available data.

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

fix: kw41z: Use correct mapping for dBm
Was using SYS_LOG_INFO and should be using LOG_INFO.
Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
The radio API expects the setting of the TX-power in dBm. The actual
TX-power is however set by a 6bit register, which mapping between
register value and power in dBm is a lookup-table in the datasheet.
This mapping for the kw41z was off, which not only lead to incorrect
output power, but also to a maximal output power of only -1.9 dBm
instead of the possible +3.5 dBm.

- Removed some debug output and changed the level of others to reduce
the amount of information logged. The reason is that some of this is
causing false positive distractions.
- Removed enabling of FILTER error IRQ events. It isn't needed and is
only informational.
- Changed frame control AR bit inspection to use native retrieval
routine.
- Addressed some coding style issues.

- Reworked the driver logic around TX/RX to correctly handle the
expectations of the underlying 802.15.4 hardware IP.
- Fixed a problem with TX always reporting an error to the stack
which resulted in constant retries.
- Fixed bug in RX to TX transition which would occasionally cause the
driver to error the TX.
- Changed RX logic to ensure that invalid RX frames were not passed up
the stack.
- Simplified hardware timer usage to only use TMR3.
- Added RX watermark and TMR3 support to fix a hardware problem where
the hw IP can get stuck on a receive in noisy environments.
- Modified samples/net/echo_client and echo_server kw41z project config
files to provide enanced debug visibility into stacks and threads.

Add support for KW40Z in the KW41Z IEEE 802.15.4 driver as both chips
expose almost the same radio registers.
Signed-off-by: Bogdan Davidoaia <bogdan.davidoaia@linaro.org>
The chip seems to require a wait time before reading packet
data after the RX sequence done interrupt, as imidiate reading
of it will indicate a packet size of zero and cause the RX
sequence done to be continually retriggered.
In addition, the extra clearing of the interrupt flags can be
removed, as this is already done at the beginning of the isr.
