This changes how ip(6)table nat passes the ruleset/table to the evaluation loop. At the moment, it will fetch the table from struct net. This change stores the table in the hook_ops 'priv' argument instead. This requires to duplicate the hook_ops for each netns, so they can store the (per-net) xt_table structure. The dupliated nat hook_ops get stored in net_generic data area. They are free'd in the namespace exit path. This is a pre-requisite to remove the xt_table/ruleset pointers from struct net.

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.
