This patch updates the way in which the tunnel neighbour entries are handled. Previously they were mostly send-and-forget, with just the destination IP's cached in a list. This update changes to a scheme where the neighbour entry information is stored in a hash table. The reason for this is that the neighbour table will now also be used on the decapsulation path, whereas previously it was only used for encapsulation. We need to save more of the neighbour information in order to link them with flower flows in follow up patches. Updating of the neighbour table is now also handled by the same function, instead of separate *_write_neigh_vX functions.

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.
