In case native IPv6 is disabled, Kconfig entries related to native IPv6
stack should not be enabled. Otherwise, circular dependencies can be
created if native stack is disabled, as in case of recent changes in
NET_IPV6_RA_RDNSS option (where a dependency for a native stack module
was enabled).

The TX timeout configured with SO_SNDTIMEO on a socket did not work
properly. If the timeout was set on a socket, the TX would work as if
the socket was put into non-blocking mode. This commit fixes this.

The timeout recalculation logic was duplicated across several routines,
therefore it makes sense to make a helper function out of it,
especially, that the same functionality would be needed for the send

SO_RCVBUF option processing at the TCP level was broken. The option
value was only checked once, when the TCP context was allocated. This
made little sense, as at this point the option would not even get a
chance to have custom value. If the user modified the option after the
socket (net_context) was created, it had no effect on the TCP operation.
This commit fixes this, by checking the option value whenever new packet
is processed, so that the configured window size is updated at the TCP
level before we report it in the TCP ACK. In order to achieve this,
introduce a new helper function, to refresh the configured window sizes,
to avoid bloating `tcp_in()` even further.

In order to take granular input use micro seconds as input for TWT
intervals, this helps us in providing inputs such as 65.28ms without the
need of using floating points.
This also expands the TWT wake interval range to 262.144ms, earlier as
we want to use uint8, limited to 256ms.
Also, remove the units from the variable names, this is unnecessary and
also avoids doing breaking changes.
Update release notes as this is a breaking change, both type and
variable names are changed.

Currently the zperf_tcp_receiver can handle only one TCP connection
each time, modify the code to poll and handle multiple connections.
Take the occasion to unify the bind and listen part of the code
between ipv4 and ipv6 part using a structure introduced to handle
the multiple connections.
Now in case the zsock_recv fails, we can't stop every connection
and fail through the error label, so just print the error message
and report the failure through the callback.

Provide a means of declaring zero or more HTTP services, each
with zero or more static HTTP resources.
Static HTTP resources are those which have fixed paths[1] which
are known prior to system initialization. Some examples of
static http resources would be
* a forwarder from '/' to '/index.html'
* a REST endpoint with fixed path '/api/foo' and detail
pointing at some implementation-specific function
* a Javascript file in string form with fixed path '/js/util.js'
* a 'construction' image with path '/res/work.png'
* a gzip-compressed 'Hello' HTML file at '/hello.html'
Without describing in any detail how static HTTP resources are
organized or served by any given HTTP server, we can describe
what static resources exist on a system in a common way that
does not require any optional facilities (e.g. filesystem) and
relies only on addressable memory.
Additionally, for the purposes of simply allowing others
to implement custom HTTP servers in a consistent way, or
benchmarking implementations, or having a consistent testsuite
to use across multiple implementations, it is helpful to have
a common method to declare HTTP services and static resources
for Zephyr.

Packet handlers registered with net_conn API should not use NET_CONTINUE
to report packet processing status. As they register for a specific
local port, it cannot be assumed someone else will handle the packet,
and for net_conn this status is not really handled differently from
NET_OK. Therefore, reporting NET_CONTINUE, and not freeing the packet,
can result in a packet leak.
Too short packets should not really be handled differently from other
malformed packets in DHCPv4 module, therefore report NET_DROP instead of
NET_CONTINUE.

Currently, in tcp_received function defined in zperf_tcp_receiver
module, the assignment of session->state to STATE_COMPLETED is
overwritten on the same path to STATE_NULL and a session is
considered free for both STATE_COMPLETED and STATE_NULL, so remove

TCP implementation abused the packet processing result reporting
mechanism, by reporting NET_DROP for every packet other than data
packets (which were passed to the application). This simplified the TCP
implementation a bit, as it didn't need to deal with packet releasing.
While technically it worked, it gave incorrect results when it comes to
packet statistics, as a lot of valid TCP packets were counted as
dropped.
This commit fixes this. Each packet that was properly processed by the
TCP stack is not either released at the TCP level, or passed to the
application. In both cases, NET_OK is returned to the network core,
indicating the packet has been properly processed and consumed.

In the case of no ARP entry, the incoming packet is added to the ARP's
pending queue, while ARP is being resolved. Here a reference is taken
by the ARP layer to the packet to avoid it being freed, but the Ethernet
immediately puts down the reference and send the ARP packet to the
driver.
If the ARP request fails for some reason, L2 returns failure to net_if
which then puts down the reference and the packet will be freed as the
reference count is now zero.
But the packet is still in the ARP's pending queue and after timeout
ARP will put down the reference causing double free bus fault (double
free message is only seen if the CONFIG_NET_PKT_LOG_LEVEL_DBG is
enabled, so, a bit hard to debug.
Fix this by clearing the ARP entry and pending queue after taking a
reference and then free ARP packet, IP packets are either freed by ARP
pending queue drain or net_if layer.
