Refactor the send_msg_fragmented() function by extracting the logic for
sending the message body into a new function called
send_fragmented_body().
Now, send_msg_fragmented() handles appending the release and header, and
then delegates the task of breaking up the body and sending the
fragments to send_fragmented_body().
This is the final flow now:
When send_ext_msg_udp() is called to send a message, it will:
- call send_msg_no_fragmentation() if no fragmentation is needed
or
- call send_msg_fragmented() if fragmentation is needed
* send_msg_fragmented() appends the header to the buffer, which is
be persisted until the function returns
* call send_fragmented_body() to iterate and populate the body of
the message. It will not touch the header, and it will only
replace the body, writing the msgbody and/or userdata.
Also add some comment to make the code easier to review.

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 reStructuredText 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.
