Pull networking fixes from David Miller:

 1) Fix erroneous sock_orphan() leading to crashes and double
    kfree_skb() in NFC protocol.  From Thierry Escande and Samuel Ortiz.

 2) Fix use after free in remain-on-channel mac80211 code, from Johannes
    Berg.

 3) nf_reset() needs to reset the NF tracing cookie, otherwise we can
    leak it from one namespace into another.  Fix from Gao Feng and
    Patrick McHardy.

 4) Fix overflow in channel scanning array of mwifiex driver, from Stone
    Piao.

 5) Fix loss of link after suspend/shutdown in r8169, from Hayes Wang.

 6) Synchronization of unicast address lists to the undelying device
    doesn't work because whether to sync is maintained as a boolean
    rather than a true count.  Fix from Vlad Yasevich.

 7) Fix corruption of TSO packets in atl1e by limiting the segmented
    packet length.  From Hannes Frederic Sowa.

 8) Revert bogus AF_UNIX credential passing change and fix the
    coalescing issue properly, from Eric W Biederman.

 9) Changes of ipv4 address lifetime settings needs to generate a
    notification, from Jiri Pirko.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (22 commits)
  netfilter: don't reset nf_trace in nf_reset()
