From POSIX.1-2017:
The getsockname() function shall retrieve the locally-bound name of the
specified socket, store this address in the sockaddr structure pointed
to by the address argument, and store the length of this address in the
object pointed to by the address_len argument.
The address_len argument points to a socklen_t object which on input
specifies the length of the supplied sockaddr structure, and on output
specifies the length of the stored address. If the actual length of the
address is greater than the length of the supplied sockaddr structure,
the stored address shall be truncated.
If the socket has not been bound to a local name, the value stored in
the object pointed to by address is unspecified.

Libraries that use mbedTLS have been invoking
zephyr_link_interface(mbedTLS). It is not clear what the intent of
this code has been, but it is redundant with the mbedTLS build
scripts, so it can be safely removed.
In addition to being redundant, it causes problems as it introduces an
ordering dependency, with this code mbedTLS must be declared before
users of mbedTLS are declared. Since this code is redundant, this
ordering dependency is also unnecessary.
This code is believed to have been added early on by accident and
copied through cargo-cult programming since.

sntp_simple() function queries the server (passed as "addr[:port]"

Two utils to manipulate addresses in format "addr[:port]". I.e.,
network address (domain name or numeric), optionally followed by
port number:
* net_addr_str_find_port(), to return pointer to port number
substring (or NULL if not present).
* net_getaddrinfo_addr_str(), which is effectively getaddrinfo()
wrapper taking a "addr[:port]" string as a parameter.
The header file is named socketutils.h to emphasize that these
utility functions are implemented on top of BSD Sockets API
(and other POSIX/ANSI C functions), and thus portable to other
POSIX systems (e.g., Linux), so can be used in apps testing
POSIX compatibility. More utility functions (beyond address
manipulation) can be added later.

Calling functions like `net_if_start_dad`, `join_mcast_nodes` or
`net_if_start_rs` lead to L2 API function calls, which is not correct
for offloaded interfaces and leads to a crash. This is especially
problematic, as they are called in the default configuration.
Avoid calling these functions while an offloaded interface is brought up
by adding extra jump label.

It is possible that the device driver API pointer is null.

There were various flaws in it that motivated its removal:
- No hash collision handling mechanism. In case that would happen, the
behavior of the network connection would be unknown. This is the main
drawback
- The lookup is not that much more efficient than the default one. The
only difference of gain is in connection comparison (a u32t comparison
vs a full connection compare). But the list handling is the same. It's
made worse by the presence of a negatives match array which can be
easily filled in and becomes then fully usless, appart from consuming
CPU. As well as adding a new connection: it requires the whole cache
to be cleared which is unefficient.
- Not memory efficient, even compared to a proper hash table.
Two arrays instead of one etc...
All of this could be fixed by using a proper hash table, though it
remains to be seen if such object could fit in Zephyr core.

The source address in unicast DHCPv4 Request packets was found out
to be all zeros address 0.0.0.0. This address is only acceptable if
the destination is a multicast one, where the host in question is
acquiring a DHCP address lease. This is true for the DHCP Discover
and the initial DHCP Request message from the client towards the
server. As subsequent DHCP Request renewal messages are sent as
unicast to the server, the server will drop such packets.
Fix this issue by explicitely specifying what source IP address is
to be used, if none is specified, the all zeros address 0.0.0.0 is
used in multicast addresses. The source address in the other
unicast cases is identical to the 'ciaddr' in the DHCP message.
