Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from David Miller:

 1) Fix some length checks during OGM processing in batman-adv, from
    Sven Eckelmann.

 2) Fix regression that caused netfilter conntrack sysctls to not be
    per-netns any more. From Florian Westphal.

 3) Use after free in netpoll, from Feng Sun.

 4) Guard destruction of pfifo_fast per-cpu qdisc stats with
    qdisc_is_percpu_stats(), from Davide Caratti. Similar bug is fixed
    in pfifo_fast_enqueue().

 5) Fix memory leak in mld_del_delrec(), from Eric Dumazet.

 6) Handle neigh events on internal ports correctly in nfp, from John
    Hurley.

 7) Clear SKB timestamp in NF flow table code so that it does not
    confuse fq scheduler. From Florian Westphal.

 8) taprio destroy can crash if it is invoked in a failure path of
    taprio_init(), because the list head isn't setup properly yet and
    the list del is unconditional. Perform the list add earlier to
    address this. From Vladimir Oltean.

 9) Make sure to reapply vlan filters on device up, in aquantia driver.
    From Dmitry Bogdanov.

10) sgiseeq driver releases DMA memory using free_page() instead of
    dma_free_attrs(). From Christophe JAILLET.
