Sven Eckelmann fa88c65601 batman-adv: dat: prevent false sharing between VLANs
commit 20d7658b74 upstream.

The local hash of DAT entries is supposed to be VLAN (VID) aware. But
the adding to the hash and the search in the hash were not checking the VID
information of the hash entries. The entries would therefore only be
correctly separated when batadv_hash_dat() didn't select the same buckets
for different VIDs.

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.
