The kernel has xmit_more facility that hints the networking driver xmit path about whether more packets are coming soon. This information can be used to avoid unnecessary expensive PCIe transaction per tx packet. Max TX pps on Mikrotik 10/25G NIC in a Threadripper 3960X system improved from 1150Kpps to 1700Kpps. Testing L2 forwarding on AR8151 hardware did not reveal a measurable increase in latency. Signed-off-by: Gatis Peisenieks <gatis@mikrotik.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
