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

Pull networking fixes from David Miller:

 1) Fix a reference to a module parameter which was lost during the
    GREv6 receive path rewrite, from Alexey Kodanev.

 2) Fix deref before NULL check in ipheth, from Gustavo A. R. Silva.

 3) RCU read lock imbalance in tun_build_skb(), from Xin Long.

 4) Some stragglers from the mac80211 folks:

      a) Timer conversions from Kees Cook

      b) Fix some sequencing issue when cfg80211 is built statically,
         from Johannes Berg

      c) Memory leak in mac80211_hwsim, from Ben Hutchings.

 5) Add new qmi_wwan device ID, from Sebastian Sjoholm.

 6) Fix use after free in tipc, from Jon Maloy.

 7) Missing kdoc in nfp driver, from Jakub Kicinski.
