Add position handle to allow to identify the rule location from netlink
events. Otherwise, userspace cannot incrementally update a userspace
cache through monitoring events.
Skip handle dump if the rule has been either inserted (at the beginning
of the ruleset) or appended (at the end of the ruleset), the
NLM_F_APPEND netlink flag is sufficient in these two cases.
Handle NLM_F_REPLACE as NLM_F_APPEND since the rule replacement
expansion appends it after the specified rule handle.

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.
