Tomasz Bursztyka e5896906f6 net: Rename all *_BUF() macros to *_HDR()
Most of these macros are not exactly exposing a buffer, but a specific
header pointer (ipv6, ivp4, ethernet and so on), so it relevant to
rename them accordingly.

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.

Jukka Rissanen 4eb2020055 net: Set the network link address type when setting link address
The interface L2 address type is set at the same time as the
L2 address is set to the network interface. This is most
convinient place to set the address type.

Use printk(), snprintk() instead of printf() and snprintf().
CONFIG_STDOUT_CONSOLE is anyway disabled by default so printf()
will not output anything without it.

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.

Luiz Augusto von Dentz 8a16c6681a net: l2: Add enable callback
This adds enable callback which can be used to notify the L2 driver about
changes of interface state, the L2 driver can then check if the new state
is allowed and reject otherwise.

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.

Tomasz Bursztyka ff5954890a net: ethernet: IPv6 packet length should be relevantly handled
It's much different than IPv4 where it's possible to find the whole
packet length. Here it has to count also the ipv6 header size by itself.

Tomasz Bursztyka cff19c17c4 net: l2: ethernet: Handle Ethernet II minimal frame size relevantly
Minimal frame size is 60 bytes, but IP frame might be smaller than this
size minus the ethernet header. In that case, Ethernet frames are padded
so it does reach this minimal size. In this case, ethernet L2 should
update the buffer list so it remove the padding length from the whole.
