====================
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
      由 Sergei Shtylyov 提交于 
      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
      由 Yuval Mintz 提交于 
      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
      由 Yuval Mintz 提交于 
      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.

      qed: Add support for HW attentions · 0d956e8a
      由 Yuval Mintz 提交于 
      HW is capable of generating attentnions for a multitude of reasons,
but current driver is enabling attention generation only for management
firmware [required for link notifications].

This patch enables almost all of the possible reasons for HW attentions,
logging the HW block generating the attention and preventing further
attentions from that source [to prevent possible attention flood].
It also lays the infrastructure for additional exploration of the various
attentions.
