Data centric bridging designed to eliminate packet loss due to queue overflow by adding enhancements to ethernet network such as proprity flow control etc. This patch adds support for management of Priority flow control(PFC) on Octeontx2 and CN10K interfaces. To enable PFC for all priorities dcb pfc set dev eth0 prio-pfc all:on/off To enable PFC on selected priorites dcb pfc set dev eth0 prio-pfc 0:on/off 1:on/off ..7:on/off With the ntuple commands user can map Priority to receive queues. On queue overflow NIX will assert backpressure such that PFC pause frames are genarated with mapped priority. To map priority 7 to Queue 1 ethtool -U eth0 flow-type ether dst xx:xx:xx:xx:xx:xx vlan 0xe00a m 0x1fff queue 1 Signed-off-by: Hariprasad Kelam <hkelam@marvell.com> Signed-off-by: Sunil Kovvuri Goutham <sgoutham@marvell.com> Signed-off-by: David S.

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.
