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

Pull networking fixes from David Miller:

 1) Need to save away the IV across tls async operations, from Dave
    Watson.

 2) Upon successful packet processing, we should liberate the SKB with
    dev_consume_skb{_irq}(). From Yang Wei.

 3) Only apply RX hang workaround on effected macb chips, from Harini
    Katakam.

 4) Dummy netdev need a proper namespace assigned to them, from Josh
    Elsasser.

 5) Some paths of nft_compat run lockless now, and thus we need to use a
    proper refcnt_t. From Florian Westphal.

 6) Avoid deadlock in mlx5 by doing IRQ locking, from Moni Shoua.

 7) netrom does not refcount sockets properly wrt. timers, fix that by
    using the sock timer API. From Cong Wang.

 8) Fix locking of inexact inserts of xfrm policies, from Florian
    Westphal.

 9) Missing xfrm hash generation bump, also from Florian.

10) Missing of_node_put() in hns driver, from Yonglong Liu.

11) Fix DN_IFREQ_SIZE, from Johannes Berg.

12) ip6mr notifier is invoked during traversal of wrong table, from Nir
    Dotan.

13) TX promisc settings not performed correctly in qed, from Manish
    Chopra.

14) Fix OOB access in vhost, from Jason Wang.
