This patch makes it impossible that cmpri or cmpre values are set to the value 16 which is not possible, because these are 4 bit values. We currently run in an overflow when assigning the value 16 to it. According to the standard a value of 16 can be interpreted as a full elided address which isn't possible to set as compression value. A reason why this cannot be set is that the current ipv6 header destination address should never show up inside the segments of the rpl header. In this case we run in a overflow and the address will have no compression at all. Means cmpri or compre is set to 0. As we handle cmpri and cmpre sometimes as unsigned char or 4 bit value inside the rpl header the current behaviour ends in an invalid header format. This patch simple use the best compression method if we ever run into the case that the destination address is showed up inside the rpl segments. We avoid the overflow handling and the rpl header is still valid, even when we have the destination address inside the rpl segments.

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.
