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 bf964cdd4c net: Renaming net nbuf API to net pkt API
There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.

Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).

Though net_pkt if the new name, it still inherit its logic from net_buf.
'
This patch is the first of a serie that will separate completely net_pkt
from net_buf.

If we receive lot of packets, it might happen that we exhaust
all the DATA buffers in the system. This would prevent from
us sending anything to the network.
Change this by splitting the DATA buffer pool into RX and TX
parts. This way RX flooding cannot consume all DATA buffers
that needs to be sent.

Jukka Rissanen bd3908b2a9 net: nbuf: Add timeout to net_buf getters
This commit changes the net_buf getter functions in nbuf.h
by adding a timeout parameter. These function prototypes
are changed to accept a timeout parameter.
	net_nbuf_get_rx()
	net_nbuf_get_tx()
	net_nbuf_get_data()
	net_nbuf_get_reserve_rx()
	net_nbuf_get_reserve_tx()
	net_nbuf_get_reserve_data()
	net_nbuf_copy()
	net_nbuf_copy_all()
	net_nbuf_push()
	net_nbuf_append()
	net_nbuf_write()
	net_nbuf_insert()

Following convinience functions have not been changed
	net_nbuf_append_u8
	net_nbuf_append_be16
	net_nbuf_append_be32
	net_nbuf_insert_u8
	net_nbuf_insert_be16
	net_nbuf_insert_be32
	net_nbuf_write_u8
	net_nbuf_write_be16
	net_nbuf_write_be32
so they call the base function using K_FOREVER. Use the
base function if you want to have a timeout when net_buf
is allocated.

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.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
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
line numbers in a literal include.

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.

Tomasz Bursztyka a1aa08c288 net: ip: Improve logging by adding a dedicated sys_log level
Let's make net stack having its own level of debugging through sys_log.
It replaces NET_DEBUG by NET_LOG_ENABLED, which is then semantically
better: someone wanting to log the errors might want that not only for
debugging.

Along with it, CONFIG_NET_LOG_GLOBAL option is added, in order to enable
all available logging in network stack. It is disabled by default but
might be found useful when warning/errors need to be logged, so it is
then unnecessary to selectively enable by hand all CONFIG_NET_DEBUG_*
options.

It is possible, locally, to override CONFIG_SYS_LOG_NET_LEVEL by setting
the level one want to NET_SYS_LOG_LEVEL. This can be useful on samples
or tests.
