      batman-adv 20160229
      
      this is our (hopefully) latest batch of patches intended for net-next.
      
      With this patchset we finally introduce B.A.T.M.A.N. V: the latest
      version of our routing protocol.
      Technical documentation describing the protocol in more detail can
      be found in our wiki[1][2][3][4].
      
      For what concerns this pull request, you can find the high level
      description right below.

       ...
      
      With this patchset we finally introduce our new routing protocol:
      B.A.T.M.A.N. V. Its implementation started quite some years ago,
      but due to the big changes being introduced it took a while to be
      discussed, designed, worked, re-worked, tested and debugged (well,
      we're never done with the latest). The entire operation has
      basically been a team work involving all the core contributors
      together with other people interested in the project.
      
      The new protocol is divided into two main subcomponents, called
      respectively ELP and OGMv2. The former is in charge of
      dealing with the neighbour discovery and link quality estimation,
      while the latter implements the algorithm that spreads the
      metrics around the network and computes optimal paths.
      
      The biggest change introduced with B.A.T.M.A.N. V is the new
      metric: the protocol won't rely on packet loss anymore, but it
      will use the estimated throughput extracted directly from the
      wifi driver (when available) by querying cfg80211.
      Batman-adv will also send some unicast probing packets when
      an interface is not used for payload traffic to make sure that
      such values are current.
      
      The new protocol can be compiled-in or not like other
      features we have and when selected will pull in CFG80211 as
      dependency for the reason described above.
      
      Thanks to the big work brought up in the past by Marek Lindner,
      batman-adv can easily deal several protocol implementations,
      therefore compiling in this new version does not exclude the
      older.
      This means that the user is offered the option to choose
      the protocol when creating the mesh interface (default is the
      old one to keep backward compatibility).
      
      Along with the protocol there are some sysfs knobs that are
      introduced to fine tune some of its behaviours, but users
      are recommended to keep the default values unless they know
      what they are doing.
      
      The last patch is about advertising our own patchwork platform
      (thanks to Sven Eckelmann for having set that up!) in the
      MAINTAINERS file.

      of_mdio: kill useless variable in of_mdiobus_register() · 2fca6d28
      Sergei Shtylyov authored
      of_mdiobus_register()  declares the 'paddr' variable to hold the result of
      the of_get_property()  but only uses it once after that while the function
      can be called directly from the *if* statement. Remove that variable and
      switch to calling of_find_property() instead since  we don't care about
      the "reg" property's value anyway...

      ====================
      qed: Attention support patch series
      
      Until now we've only enabled attention generation for the sake of
      management firmware indications [required for link notifications].
      
      This series enables [almost] all the attention sources of the HW,
      currently for the sake of logging information relating to issues
      experienced by HW. In future, infrastructure laid here would also be used
      for the sake of the recovery process.
      
      The first patch in the series is a semantic alignemnt of the code.
      The later 3 patches incremently create said infrastructure and enrich
      the logged information.
      Notice #3 contains quite a bit of structures [consisting of ~1K lines]
      that will eventually be removed and incorporated in the binary fw file.

      qed: Print additional HW attention info · b4149dc7
      Yuval Mintz authored
      This patch utilizes the attention infrastructure to log additional
      information that relates only to specific HW blocks.
      For some of those HW blocks, it also stops automatically disabling the
      attention generation as the attention is considered benign and thus
      should only be logged; No fear of it flooding the system.

      qed: Print HW attention reasons · ff38577a
      Yuval Mintz authored
      Each HW block contains common information about attention reasons,
      raising a bit for each one of the different sub-reasons that caused it
      to raise an attention.
      
      This patch extends the infrastructure by allowing logging of the various
      reasons causing the HW blocks to generate an attention.
