[PATCH net-next 0/8] IPv6 MLD updates

[Daniel Borkmann <dborkman@redhat.com>]

This set contains the non-RFC version of the previous submission entitled
"[RFC PATCH net-next 0/7] IPv6 MLD updates". Most importantly it contains
a fix for MLDv1/v2 switchback timeout where hosts currently are switching
back from v1 compat mode to normal v2 too early (i.e. switchback time was
<= 30secs instead of >= 260secs on default), and the set also contains a
patch that allows for v2-only mode as per RFC recommendation. The rest is
related to cleanups that make the code more readable resp. maintainable.

Changes from RFC to non-RFC:

We ignore v2 messages now when in v1 compat mode, otherwise report timers
are reset and triggered, also stop current v2 report timer in case it is
currently running and we received a v1 query; use WARN_ON instead of BUG_ON
for RV of 0 (patch1).

Two more patches have been added that makes to code more readable, that is
"net: ipv6: mld: refactor query processing into v1/v2 functions" and
"net: ipv6: mld: introduce mld_{gq,ifc,dad}_stop_timer functions", the
sysctl patch "net: ipv6: mld: restrict min/max of sysctl force_mld_version"
has been dropped as extra1 and extra2 vars are overwritten with idev and net
anyway when addrconf sysctl is registered, hence dropped for now. The rest is
unchanged, only adapted to take changes into account.

Thanks!
