Currently, rq->buff.headroom is applied to all fragments in legacy RQ. In the linear mode, there is a non-zero headroom, but there is only one fragment per packet. In the non-linear mode, the headroom is zero. This commit changes the logic to apply the headroom only to the first fragment. The current behavior remains the same for both linear and non-linear modes. However, it allows the next commit to enable headroom for the non-linear mode, which will be applied only to the first fragment.

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.
