f7d32d483f net: fix return type of net_addr_type2str
As we return stuff that is probably in the flash the return type should
be const char * and not char * as the user better doesn't try to change
them!

6049207a29 net: Add initial TX and RX traffic class support
With this commit it is possible to add priority to sent or received
network packets. So user is able to send or receive higher priority
packets faster than lower level packets.
The traffic class support is activated by CONFIG_NET_TC_COUNT option.
The TC support uses work queues to separate the traffic. The
priority of the work queue thread specifies the ordering of the
network traffic. Each work queue thread handles traffic to one specific
work queue. Note that you should not enable traffic classes unless
you really need them by your application. Each TC thread needs
stack so this feature requires more memory.

It is possible to disable transmit traffic class support and keep the
receive traffic class support, or vice versa. If both RX and TX traffic
classes are enabled, then both will use the same number of queues
defined by CONFIG_NET_TC_COUNT option.

996c6dd603 net: if: Handle new address type of NET_ADDR_OVERRIDABLE
The meaning of this address type is the same as NET_ADDR_MANUAL,
but with a provision that DHCP can override such an address.
It's intended for the usecase when there's a default static
configuration for when DHCP is not available, but DHCP should
override it.

Before going to add another address type, there was an attempt
to repurpose TENTATIVE address state, but it doesn't work as
expected, as indeed, all existing address types/states already
have clearly semantics, and it makes sense to just another
address type to avoid confusion and unexpected behavior.

ed35aa8c63 net: use UNALIGNED_ACCESS when accessing s_addr on received packets.
The offset of the IP header in a received packet depends on the L2
header size.  For Ethernet this is 14 bytes which puts the u32 IPv4
addresses on a non-u32 byte boundary.  This causes chips that don't
support unaligned access (like the Cortex-M0) to fault.

The fixes in this patch are enough to ping the board and run the
http_server sample.

753daa65f9 net: pkt: Compute TX payload data length
Compute the length of the TX payload that is transported in one
IPv4 or IPv6 datagram taking into account UDP, ICMP or TCP
headers in addition to any IPv6 extension headers added by RPL.
The TCP implementation in Zephyr is known to currently carry at
maximum 8 bytes of options. If the protocol is not known to the
stack, assume that the application handles any protocol headers
as well as the data. Also, if the net_pkt does not have a
context associated, length check on the data is omitted when
appending.

Although payload length is calculated also for TCP, the TCP MSS
value is used as before.

[] the in_addr structure [] includes at least the following member:

In other words, POSIX requires s_addr to be a single integer value,

everywhere. Fix that by following POSIX definition, which helps to

We introduce <zephyr/types.h> as part of this and have it include

types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some

incorrect behavior as the first field in a sockaddr is sa_family_t

So without special knowledge, a developer will use a sockaddr structure

set correctly.

Let's change this parameter to void * which makes this function similar

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
