Pull networking updates from David Miller:

 1) tx_filtered/ps_tx_buf queues need to be accessed with the SKB queue
    lock, from Arik Nemtsov.

 2) Don't call 802.11 driver's filter configure method until it's
    actually open, from Felix Fietkau.

 3) Use ieee80211_free_txskb otherwise we leak control information.
    From Johannes Berg.

 4) Fix memory leak in bluetooth UUID removal,f rom Johan Hedberg.

 5) The shift mask trick doesn't work properly when 'optname' is out of
    range in do_ip_setsockopt().  Use a straightforward switch statement
    instead, the compiler emits essentially the same code but without
    the missing range check.  From Xi Wang.

 6) Fix when we call tcp_replace_ts_recent() otherwise we can
    erroneously accept a too-high tsval.  From Eric Dumazet.

 7) VXLAN bug fixes, mostly to do with VLAN header length handling, from
    Alexander Duyck.

 8) Missing return value initialization for IPV6_MINHOPCOUNT socket
    option handling.  From Hannes Frederic.

 9) Fix regression in tasklet handling in jme/ksz884x/xilinx drivers,
    from Xiaotian Feng.

10) At smsc911x driver init time, we don't know if the chip is in word
    swap mode or not.  However we do need to wait for the control
    register's ready bit to be set before we program any other part of
    the chip.  Adjust the wait loop to account for this.  From Kamlakant
    Patel.

11) Revert erroneous MDIO bus unregister change to mdio-bitbang.c

12) Fix memory leak in /proc/net/sctp/, from Tommi Rantala.

13) tilegx driver registers IRQ with NULL name, oops, from Simon Marchi.

14) TCP metrics hash table kzalloc() based allocation can fail, back
    down to using vmalloc() if it does.  From Eric Dumazet.

15) Fix packet steering out-of-order delivery regression, from Tom
    Herbert.
