Subject: [PATCH] ppp: don't start IPv6 configuration on the device
If IPV6CP terminates before IPCP, pppd enters the RUNNING phase and we
start IP configuration without having an IP interface set, which
triggers assertions. Instead, reimplement stage3_ip6_config_start to
be a no-op. Note that IPv6 configuration on PPP devices has never been
supported by NM.
This is a simpler version of upstream commit dd98ada33f33 ("ppp:
introduce SetIfindex pppd plugin D-Bus method") that doesn't require
changing the internal plugin API.
