f8c9439908 net: if: Reshuffle fields in net_if and related structs
This does not save any space but sets the fields in the
structs in more natural order. Move IPv6 related
fields in net_if into internal ipv6 struct so that all
IPv6 fields are located inside one struct. Same thing
is done for IPv4 fields which are now located inside
IPv4 internal struct in net_if.

There is no functionality changes by this commit.

The Kconfig.rpl file was missing option to actually collect
RPL statistics. Unified the config option name to be
CONFIG_NET_STATISTICS_RPL as there was two conflicting settings
in the code and both of them were missing from Kconfig file.

e38a9e8b9c net: Switch from per-iface tx thread to a unique k_poll triggered one
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.

Change this by splitting the DATA buffer pool into RX and TX

be transmitted out (TX). This helps to avoid deadlocking

in the system, and the core IP stack tries to get buffer

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.

ca6a686495 net: correct in*_addr parameter of net_addr_pton()
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().

46c0997e8b net: tcp: Reduce size of state member from 32 to 4 bits
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.

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.
