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

Pull networking fixes from David Miller:

 1) Fix use-after-free with mac80211 RX A-MPDU reorder timer, from
    Johannes Berg.

 2) iwlwifi leaks memory every module load/unload cycles, fix from Larry
    Finger.

 3) Need to use for_each_netdev_safe() in rtnl_group_changelink()
    otherwise we can crash, from WANG Cong.

 4) mlx4 driver does register_netdev() too early in the probe sequence,
    from Ido Shamay.

 5) Don't allow router discovery hop limit to decrease the interface's
    hop limit, from D.S. Ljungmark.

 6) tx_packets and tx_bytes improperly accounted for certain classes of
    USB network devices, fix from Ben Hutchings.

 7) ip{6}mr_rules_init() mistakenly use plain kfree to release the ipmr
    tables in the error path, they must instead use ip{6}mr_free_table().
    Fix from WANG Cong.

 8) cxgb4 doesn't properly quiesce all RX activity before unregistering
    the netdevice.  Fix from Hariprasad Shenai.

 9) Fix hash corruptions in ipvlan driver, from Jiri Benc.

10) nla_memcpy(), like a real memcpy, should fully initialize the
    destination buffer, even if the source attribute is smaller.  Fix
    from Jiri Benc.

11) Fix wrong error code returned from iucv_sock_sendmsg().  We should
    use whatever sock_alloc_send_skb() put into 'err'.  From Eugene
    Crosser.

12) Fix slab object leak on module unload in TIPC, from Ying Xue.

13) Need a READ_ONCE() when reading the cached RX socket route in
    tcp_v{4,6}_early_demux().  From Michal Kubecek.

14) Still too many problems with TPC support in the ath9k driver, so
    disable it for now.  From Felix Fietkau.

15) When in AP mode the rtlwifi driver can leak DMA mappings, fix from
    Larry Finger.

16) Missing kzalloc() failure check in gs_usb CAN driver, from Colin Ian
    King.
