Pull networking update from David Miller:

 1) Fix dump iterator in nfnl_acct_dump() and ctnl_timeout_dump() to
    dump all objects properly, from Pablo Neira Ayuso.

 2) xt_TCPMSS must use the default MSS of 536 when no MSS TCP option is
    present.  Fix from Phil Oester.

 3) qdisc_get_rtab() looks for an existing matching rate table and uses
    that instead of creating a new one.  However, it's key matching is
    incomplete, it fails to check to make sure the ->data[] array is
    identical too.  Fix from Eric Dumazet.

 4) ip_vs_dest_entry isn't fully initialized before copying back to
    userspace, fix from Dan Carpenter.

 5) Fix ubuf reference counting regression in vhost_net, from Jason
    Wang.

 6) When sock_diag dumps a socket filter back to userspace, we have to
    translate it out of the kernel's internal representation first.
    From Nicolas Dichtel.

 7) davinci_mdio holds a spinlock while calling pm_runtime, which
    sleeps.  Fix from Sebastian Siewior.

 8) Timeout check in sh_eth_check_reset is off by one, from Sergei
    Shtylyov.

 9) If sctp socket init fails, we can NULL deref during cleanup.  Fix
    from Daniel Borkmann.

10) netlink_mmap() does not propagate errors properly, from Patrick
    McHardy.

11) Disable powersave and use minstrel by default in ath9k.  From Sujith
    Manoharan.

12) Fix a regression in that SOCK_ZEROCOPY is not set on tuntap sockets
    which prevents vhost from being able to use zerocopy.  From Jason
    Wang.

13) Fix race between port lookup and TX path in team driver, from Jiri
    Pirko.

14) Missing length checks in bluetooth L2CAP packet parsing, from Johan
    Hedberg.

15) rtlwifi fails to connect to networking using any encryption method
    other than WPA2.  Fix from Larry Finger.

16) Fix iwlegacy build due to incorrect CONFIG_* ifdeffing for power
    management stuff.  From Yijing Wang.
