Pull networking fixes from David Miller:

 1) Missed rcu_assign_pointer() in mac80211 scanning, from Johannes
    Berg.

 2) Allow devices to limit the number of segments that an individual
    TCP TSO packet can use at a time, to deal with device and/or driver
    specific limitations.  From Ben Hutchings.

 3) Fix unexpected hard IPSEC expiration after setting the date.  From
    Fan Du.

 4) Memory leak fix in bxn2x driver, from Jesper Juhl.

 5) Fix two memory leaks in libertas driver, from Daniel Drake.

 6) Fix deref of out-of-range array index in packet scheduler generic
    actions layer.  From Hiroaki SHIMODA.

 7) Fix TX flow control errors in mlx4 driver, from Yevgeny Petrilin.

 8) Fix CRIS eth_v10.c driver build, from Randy Dunlap.

 9) Fix wrong SKB freeing in LLC protocol layer, from Sorin Dumitru.

10) The IP output path checks neigh lookup errors incorrectly, it needs
    to use IS_ERR().  From Vasiliy Kulikov.

11) An estimator leak leads to deref of freed memory in timer handler,
    fix from Hiroaki SHIMODA.

12) TCP early demux in ipv6 needs to use DST cookies in order to
    validate the RX route properly.  Fix from Eric Dumazet.
