eef8e67ea7 net: ppp: ipcp: do not require a peer address
It is not unusual that the peer does not provide an IP address in the
ipcp negotiation. But because ppp is a peer-to-peer protocol, we do
not actually need to know the peer's address to use the network.

3ce7f89a8a net: pkt: Restore pkt cursor after cloning
net_pkt_clone() initializes the original packet cursor
and clone the packet. But it doesn't restore the cursor
back to original position.

Issue noticed when mDNS resolving fails when mdns responder
is also enabled.

net_conn_input(), in case of multicast packet, connection
handler clone the packet and deliver to matching handler.

Example case: dns_resolver and mdns_responder both register
handlers for 5353 port. After first clone original packet
cursor moved back to starting position. But first cloned
packet cursor is set properly. Second time cloning makes
cursor position to set to zero. Which makes second packet
handler header unpacking goes wrong.

Fixes #21970.

eddd98f811 kconfig: Replace some single-symbol 'if's with 'depends on'
I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.

There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.

The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).

Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.

Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.

Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.

The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.

(Everything above is true for choices, menus, and comments as well.)

Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.

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.

4cad0dda44 net: ipv6: When sending NS, use correct destination address
When we are about to send a NS, we should not use the destination
address as that is typically the multicast address. We should use
the target address instead.

This fixes the case where a neighbor is in incomplete state, and
we send a neighbor solicitation to find out whether the neighbor
is reachable. In this case the destination address is the solicited
node multicast address which is no use when trying to figure out
the source address.

dts.h would be another option, but DTS stands for "devicetree source"

The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.
