Peter Tirsek 6bd3d19292 netfilter: xt_socket: Fix broken IPv6 handling 
Commit 834184b1f3 ("netfilter: defrag: only register defrag
functionality if needed") used the outdated XT_SOCKET_HAVE_IPV6 macro
which was removed earlier in commit 8db4c5be88 ("netfilter: move
socket lookup infrastructure to nf_socket_ipv{4,6}.c"). With that macro
never being defined, the xt_socket match emits an "Unknown family 10"
warning when used with IPv6:

WARNING: CPU: 0 PID: 1377 at net/netfilter/xt_socket.c:160 socket_mt_enable_defrag+0x47/0x50 [xt_socket]

This patch brings the conditional back in line with how the rest of the
file handles IPv6.

README 

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.
