[ Upstream commit 098e13f5b21d3398065fce8780f07a3ef62f4812 ] ipvs relies on nf_defrag_ipv6 module to manage IPv6 fragmentation, but lacks proper Kconfig dependencies and does not explicitly request defrag features. As a result, if netfilter hooks are not loaded, when IPv6 fragmented packet are handled by ipvs only the first fragment makes through. Fix it properly declaring the dependency on Kconfig and registering netfilter hooks on ip_vs_add_service() and ip_vs_new_dest().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
