8e9e79b21d net: gptp: Separate common strings from warning messages
Save some memory and separate common string snippets from larger
strings. In this case "does not match" sub-string is printed by

net: route: Add prefix-based ipv6 multicast forwarding

This adds/reenables the feature of multicast routing/forwarding.
The forwarding decision is based on the added multicast routes

a542de46ac net: l2: ppp: add initial support for PAP authentication
This patch implements optional authentication phase, which is done
between link establishment and network phases. It is part of LCP option
negotiation to decide whether authentication is needed and which
protocol will be used. For now we add only PAP support and try to
negotiate it when some other protocol (e.g. CHAP or EAP) is proposed
earlier. For simplicity reason we only add one way authentication
support, which means that we try to authenticate to the other peer, but
do not require authentication from it.

This is an important step to make PPP work with cellular network modems,
because most of them require to provide username and password within PPP
authentication phase. Those credentials are used by modem to login to
cellular network. In most cases however it is enough to provide dummy
values, because they are not verified. For this reason and simplicity of
this patch we hardcode PAP Peer-ID and Password now.

b9caaf217e net: lwm2m: Fix Security and Server object instance matching
A proper way to match a Security object instance with a Server object
instance is via Short Server ID resource. Both coupled object instances
should carry the same value of this resource in order to me considered
matched.

This was not implemented in the LwM2M library and it was incorrectly
assumed that the Security object instance index corresponds to the
Server object instance index. While such apporach works is simple
scenario, it might yield incorrect results when bootstrap is used.

Fix this, by verifyng the Short Server ID resource in the Secuirty
instance used, and finding a matching Server instance. The server object
instance is stored for future use in the engine.

Additionally, remove an extra Server object instance that was created
when the bootstrap procedure was used. Since the boostrap Security
object instance does not have the corresponding Server object, it's
enough to have a single Server instance.

5326d11e8c net: l2: ppp: add generalized "my options" negotiation
So far there was no generalized way how to handle negotiation of "my
options" (those sent with Conf-Req packet to peer). Peer response for
proposed options and their values were not tracked in any way, so
rejected (by peer) options were sent over and over again in subsequent
Conf-Req packets. In case of IPCP it means that all sent options such as
IP_ADDRESS, DNS1, DNS2 were mandatory for being supported by peer in
order to successfully finish negotiation. For example if 'pppd' was the
configured peer (e.g. when using with QEMU and net-tools scripts),
without ms-dns being configured (which is the default), then "my
options" negotiation failed.

Introduce generalized mechanism for negotiating "my options", so it is
easier to maintain current set of supported options and easily add new
options to the implementation in future. FSM instance inititialization
function can provide information about supported "my options".
Information is is passed as a table of 'struct ppp_my_option_info'
containing:

 * option code (type),
 * callback for adding option to Conf-Req packet,
 * callback for received Conf-Ack with that option,
 * callback for received Conf-Nak with that option.

Store also runtime information about each negotiated option. First of
all remember which options have been rejected, so they are not sent to
peer once again in the next Conf-Req packet. This will solve issue with
IPCP negotiation when peer doesn't support DNS1 or DNS2 options. Keep
also track about which options have been acked, so such information can
be verified before bringing FSM instance up.
