The batman-adv netlink messages often contain the interface index and interface name in the same message. This makes it easy for the receiver to operate on the incoming data when it either needs to print something or needs to operate on the interface index. But one of the attributes was missing for: * neighbor table dumps * originator table dumps * gateway list dumps * query of hardif information * query of vid information The userspace therefore had to implement special workarounds using SIOCGIFNAME or SIOCGIFINDEX depending on what was actually provided. Providing both information simplifies the userspace code massively without adding a lot of extra overhead in the kernel portion.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
