There are too many individual requests for Qav related parameters. There
are more Qav parameters that need to be supported (and will be supported
soon - both on the GET and SET side). Handling it the way it was handled
so far would render the eth mgmt API dominated by Qav parameters. That
would make the file hard to read and understand.
Instead of that - use a single GET and SET requests for all Qav
parameters. This works by adding a separate enum with Qav request type
to the ethernet_qav_param struct.
Additionally this approach makes it much easier to document it all since
we now have just a single request and documentation comments in the

Instead of always allocating both IPv6 and IPv4 address information
to every network interface, allow more fine grained address
configuration. So it is possible to have IPv6 or IPv4 only network
interfaces.
This commit introduces two new config options:
CONFIG_NET_IF_MAX_IPV4_COUNT and CONFIG_NET_IF_MAX_IPV6_COUNT
which tell how many IP address information structs are allocated
statically. At runtime when network interface is setup, it is then
possible to attach this IP address info struct to a specific
network interface. This can save considerable amount of memory
as the IP address information struct can be quite large (depends
on how many IP addresses user configures in the system).
Note that the value of CONFIG_NET_IF_MAX_IPV4_COUNT and
CONFIG_NET_IF_MAX_IPV6_COUNT should reflect the estimated number of
network interfaces in the system. So if if CONFIG_NET_IF_MAX_IPV6_COUNT
is set to 1 and there are two network interfaces that need IPv6
addresses, then the system will not be able to setup IPv6 addresses to
the second network interface in this case. This scenario might be
just fine if the second network interface is IPv4 only. The net_if.c
will print a warning during startup if mismatch about the counts and
the actual number of network interface is detected.

Before going to add another address type, there was an attempt

have clearly semantics, and it makes sense to just another
address type to avoid confusion and unexpected behavior.

For stream-based protocols (TCP), adding less data than requested
("short write") is generally not a problem - the rest of data can
be sent in the next packet. So, make net_pkt_append() return length
of written data instead of just bool flag, which makes it closer
to the behavior of POSIX send()/write() calls.
There're many users of older net_pkt_append() in the codebase
however, so net_pkt_append_all() convenience function is added which
keeps returning a boolean flag. All current users were converted to
this function, except for two:
samples/net/http_server/src/ssl_utils.c
samples/net/mbedtls_sslclient/src/tcp.c
Both are related to TLS and implement mbedTLS "tx callback", which
follows POSIX short-write semantics. Both cases also had a code to
workaround previous boolean-only behavior of net_pkt_append() - after
calling it, they measured length of the actual data added (but only
in case of successful return of net_pkt_append(), so that didn't
really help). So, these 2 cases are already improved.

Now that k_poll landed in the kernel, it's worth using it to save
memory and reduce the number of threads at runtime.
Such switch has been first done in bluetooth (see hci_core.c and conn.c
in subsys/bluetooth/host). Since network interfaces kind of follows the
same design for sending data, it was then easy to copy the same change as
in bluetooth.

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.

User can configure its own pools for data that needs to
be transmitted out (TX). This helps to avoid deadlocking
the system if user space application uses all the buffers
in the system, and the core IP stack tries to get buffer
that needs to be sent out.
By default the net_buf pool support in net_context is turned
off as application developer needs to create the pools and
tie them to desired contexts.

Currently, the function accepts a struct sockaddr * but the code
immediately type casts this to either in_addr or in6_addr. This is
incorrect behavior as the first field in a sockaddr is sa_family_t
and not address data.
So without special knowledge, a developer will use a sockaddr structure
as the parameter and then wonder why the address information isn't being
set correctly.
Let's change this parameter to void * which makes this function similar
to inet_pton().

No more than 4 bits are necessary to store the state of a TCP connection,
so better pack it using bitfields so that it uses only 4 bits instead of
32, by sharing space with `retry_timeout_shift` and `flags` fields.
There are 12 (or 14, if you count the 2 unused bits in the `flags`
field) bits remaining in the same dword, but I don't know what to to
stuff there yet.
This also changes all direct field access for the `state` field to
function calls. These functions are provided as `static inline`
functions and they perform only casts, so there's no function call
overhead.

This frees up some more memory as well, by computing the maximum segment
size whenever needed. A flag is set in the TCP context to signal if
the value has been already computed.

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.

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.

This moves the shell component into its own subsys and groups all
related files and options into a single place.
Additionally, one Kconfig option will now be required to enable the
shell:
CONFIG_CONSOLE_SHELL=y
The header files was also moved to include/shell/shell.h and can be now
referenced with
#include <shell/shell.h>
instead of
#include <misc/shell.h>
