Pablo Neira Ayuso says:
====================
Netfilter updates for net-next
This a bit large (and late) patchset that contains Netfilter updates for
net-next. Most relevantly br_netfilter fixes, ipset RCU support, removal of
x_tables percpu ruleset copy and rework of the nf_tables netdev support. More
specifically, they are:
1) Warn the user when there is a better protocol conntracker available, from
Marcelo Ricardo Leitner.
2) Fix forwarding of IPv6 fragmented traffic in br_netfilter, from Bernhard
Thaler. This comes with several patches to prepare the change in first place.
3) Get rid of special mtu handling of PPPoE/VLAN frames for br_netfilter. This
is not needed anymore since now we use the largest fragment size to
refragment, from Florian Westphal.
4) Restore vlan tag when refragmenting in br_netfilter, also from Florian.
5) Get rid of the percpu ruleset copy in x_tables, from Florian. Plus another
follow up patch to refine it from Eric Dumazet.
6) Several ipset cleanups, fixes and finally RCU support, from Jozsef Kadlecsik.
7) Get rid of parens in Netfilter Kconfig files.
8) Attach the net_device to the basechain as opposed to the initial per table
approach in the nf_tables netdev family.
9) Subscribe to netdev events to detect the removal and registration of a
device that is referenced by a basechain.
