This patch exposes a new API to refragment a skbuff. This allows you to split either a linear skbuff or to force the refragmentation of an existing fraglist using a different mtu. The API consists of: * ip_frag_init(), that initializes the internal state of the transformer. * ip_frag_next(), that allows you to fetch the next fragment. This function internally allocates the skbuff that represents the fragment, it pushes the IPv4 header, and it also copies the payload for each fragment. The ip_frag_state object stores the internal state of the splitter. This code has been extracted from ip_do_fragment(). Symbols are also exported to allow to reuse this iterator from the bridge codepath to build its own refragmentation routine by reusing the existing codebase.

README
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.
