Externally visible functions should be documented with kernel-doc. This
usually refers to non-static functions but also static inline files in
headers are visible in other files and should therefore be documented.

The inline kernel-doc comments make it easier to keep changes to the
struct/enum synchronized with the documentation of the it. And it makes it
easier for larger structures like struct batadv_priv to read the
documentation inside the code.

The "Linux kernel licensing rules" require that each file has a SPDX
license identifier as first line (and sometimes as second line).
The FSFE REUSE practices [1] would also require the same tags but have no
restrictions on the placement in the source file. Using the "Linux kernel
licensing rules" is therefore also fulfilling the FSFE REUSE practices
requirements at the same time.

An argument of a macro should not be evaluated multiple times. Otherwise
embedded operations in these arguments will be executed multiple times.

Mostly simple overlapping changes.
For example, David Ahern's adjacency list revamp in 'net-next'
conflicted with an adjacency list traversal bug fix in 'net'.

It must be avoided that arguments to a macro are evaluated ungrouped (which
enforces normal operator precendence). Otherwise the result of the macro
is not well defined.

The BATADV_DBG_ALL has to contain the bit of BATADV_DBG_TP_METER to really
support all available debug messages.

The throughput meter module is a simple, kernel-space replacement for
throughtput measurements tool like iperf and netperf. It is intended to
approximate TCP behaviour.
It is invoked through batctl: the protocol is connection oriented, with
cumulative acknowledgment and a dynamic-size sliding window.
The test *can* be interrupted by batctl. A receiver side timeout avoids
unlimited waitings for sender packets: after one second of inactivity, the
receiver abort the ongoing test.

There are several places in batman-adv which provide logging related
functions. These should be grouped together in the log.* files to make them
easier to find.
