Similar to Sphinx, @kconfig{} alias should be used in Doxygen docstring
in order to reference a Kconfig option. @option{} is still kept for

958e826b69 net: socket: Workaround issue with recent GCC and fcntl macro
If we have CONFIG_NET_SOCKETS_POSIX_NAMES enabled (which is now
default), and also have CONFIG_NEWLIB_LIBC enabled, latest versions
of GCC throw a strange error like:

error: conflicting types for 'zsock_fcntl'
  692 | #define fcntl zsock_fcntl

After enough consideration, it seems that when Newlib is used, its
fcntl.h header is used, which declares fcntl() with POSIX prototype:
"int fcntl(int fd, int cmd, ...)". It seems that recent GCC, when
seeing the #define like above, checks that its right-hand side
(zsock_fcntl(int, int, int) above) is compatible with an existing
LHS prototype. That doesn't make sense from the point of view of
the C preprocessor semantics, and yet that's what apparently happens.

Make GCC happy by defining an inline wrapper function with
signature compatible with POSIX fcntl prototype, and use it in
the define, instead of zsock_fcntl directly.

814fb71bf3 net: socket: Implement SO_BINDTODEVICE socket option
Implement SO_BINDTODEVICE socket option which allows to bind an open
socket to a particular network interface. Once bound, the socket will
only send and receive packets through that interface.

For the TX path, simply avoid overwriting the interface pointer by
net_context_bind() in case it's already bound to an interface with an
option. For the RX path, drop the packet in case the connection handler
detects that the net_context associated with that connection is bound to
a different interface that the packet origin interface.

bea1093e62 net: sockets: Remove socket offloading interface
Instead of using a custom offloading interface, users can use
`NET_SOCKET_REGISTER` macro to register custom socket API provider. This
solution removes a limitation, that only one offloaded interface can be
registered and that it cannot be used together with native IP stack.

The only exception remainig are DNS releated operations -
`getaddrinfo`/`freeaddrinfo`, which, when offloaded, have to be
registered specifically.

c0b30355fb net: sockets: implement getsockname function
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.

Not in POSIX. Linux man getnameinfo says about it:

Since glibc 2.8, these definitions are exposed only if suitable
feature test macros are defined, namely: _GNU_SOURCE, _DEFAULT_SOURCE
(since glibc 2.19), or (in glibc versions up to and including 2.19)
_BSD_SOURCE or _SVID_SOURCE."

So, for now follow the existing route of duplicating all definitions

subsystem to work with POSIX subsystem, but that's a separate deep

3fd89baca4 net: Fix inet_pton when offloading is enabled

In this commit, we have chosen to directly call net_addr_pton() in
