When processing a TSO we may have frags spread across several descriptors, and the total count of frags in one skb may exceed our per descriptor IONIC_MAX_FRAGS: this is fine as long as each descriptor has fewer frags than the limit. Since the skb could have as many as MAX_SKB_FRAGS, and the first descriptor is where we track and map the frag buffers, we need to be sure we can map buffers for all of the frags plus the TSO header in the first descriptor's buffer array.

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.
