The batadv interfaces are virtual interfaces which just tunnel the traffic over other ethernet compatible interfaces. It doesn't need serialization during the tx phase and is using RCU for most of its internal datastructures. Since it doesn't have actual queues which could be locked independently, the throughput gets significantly reduced by the extra lock in the core net code. 8 parallel TCP connections forwarded by an IPQ4019 based hardware over 5GHz could reach: * without LLTX: 349 Mibit/s * with LLTX: 563 Mibit/s Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Simon Wunderlich <sw@simonwunderlich.de>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
