Robert Lubos 635191ac8c net: ieee802154: Fix ack check
15.4 MHR is no longer set in net_buf pointed by net_pkt, but in a
separate net_buf, hence we need to check that net_buf now to
determine if we need to wait for ACK or not.

Tomasz Bursztyka ebb40ba338 net/ieee802154: Switch to L2 sending path
As for Ethernet, up to ieee802154 L2's send to actually sent the packet.
It's currently unoptimized as 6lo compression, 15.4 fragmentation and so
on will reallocate net_buf etc... but it's the first step towards
removing ll reserve space and more.

Applying changes to Openthread L2 as well.

Tomasz Bursztyka 9aa2f45d23 net/ieee802154: Add Sub-Ghz dedicated function on the radio API
Sub-Ghz bands have different limit of channels. 10, or more than a
thousand is actually possible. Thus the device needs to expose such
limit to the L2 which is unaware of frequency band logic. L2 will
then allow user to select a proper channel.

Tomasz Bursztyka db11fcd174 net/net_pkt: Fully separate struct net_pkt from struct net_buf
- net_pkt becomes a stand-alone structure with network packet meta
  information.
- network packet data is still managed through net_buf, mostly named
  'frag'.
- net_pkt memory management is done through k_mem_slab
- function got introduced or relevantly renamed to target eithe net_pkt
  or net_buf fragments.
- net_buf's sent_list ends up in net_pkt now, and thus helps to save
  memory when TCP is enabled.

Tomasz Bursztyka 83ed3a29be net/ieee802154: Modify radio TX function signature
The cause for this change is TCP. Until now, the radio strategy driver
(ALOHA or CSMA) was providing the actual nbuf, and not the buffer
fragment, counting on the fact that the loop was using
net_buf_frag_del() which made so, iteration after iteration, buffer
framgent to be always buf->frags. The problem with this logic is loosing
the fragments that might be still referenced by TCP, in case the whole
buffer did not make it so TCP can retry later and so on.

Instead, TX now takes the nbuf and the actual frag to send. It could
have been working with just a pointer on the data, and the whole length
of the frame. But it has been avoided due to possible future devices,
that will be smarter and run CSMA directly in the hw, thus it will
require to access the whole buffer list through the nbuf.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.
