Sven Eckelmann 9bd50100ee batman-adv: Ignore own maximum aggregation size during RX
commit 548b0c5de7619ef53bbde5590700693f2f6d2a56 upstream.

An OGMv1 and OGMv2 packet receive processing were not only limited by the
number of bytes in the received packet but also by the nodes maximum
aggregation packet size limit. But this limit is relevant for TX and not
for RX. It must not be enforced by batadv_(i)v_ogm_aggr_packet to avoid
loss of information in case of a different limit for sender and receiver.

This has a minor side effect for B.A.T.M.A.N. IV because the
batadv_iv_ogm_aggr_packet is also used for the preprocessing for the TX.
But since the aggregation code itself will not allow more than
BATADV_MAX_AGGREGATION_BYTES bytes, this check was never triggering (in
this context) prior of removing it.

README

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.
