This patch restores cake's deployed behavior at line rate to always
split gso, and makes gso splitting configurable from userspace.
running cake unlimited (unshaped) at 1gigE, local traffic:
no-split-gso bql limit: 131966
split-gso bql limit: ~42392-45420
On this 4 stream test splitting gso apart results in halving the
observed interpacket latency at no loss in throughput.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
