[lwip-devel] [bug #56016] IPv6 auto configuration need some optimization

[Gao Qingshui]

Follow-up Comment #1, bug #56016 (project lwip):

update the statement in the 1st comment:
1, for the 2nd item, when enable auto configuration, RFC4862 also suggest to
send RS. pls refer RFC4862 section 5.5.1, "Router Advertisements are sent
periodically to the all-nodes multicast address. To obtain an advertisement
quickly, a host sends out Router Solicitations as described in [RFC4861]."
2, for the 3rd item, when disable auto configuration, I think maybe I am
wrong, the auto configurated address could be still usable until invalid timer
trigged. RFC4862 has no statement on this scenario.
3, in order to make lwip works well in Plug-and-Play scenario, I recommend to
fix the issue bug#55602 to handle the case that host switch from one subnet to
another.
