Add support for programming the HW MCAM match key with IP tos, IP(v6) proto icmp/icmpv6, allowing flow offload rules to be installed using those fields. The NPC HW extracts layer type, which will be used as a matching criteria for different IP protocols. The ethtool n-tuple filter logic has been updated to parse the IP tos and l4proto for HW offloading. l4proto tcp/udp/sctp/ah/esp/icmp are supported. See example usage below. Ex: Redirect l4proto icmp to vf 0 queue 0 ethtool -U eth0 flow-type ip4 l4proto 1 action vf 0 queue 0 Ex: Redirect flow with ip tos 8 to vf 0 queue 0 ethtool -U eth0 flow-type ip4 tos 8 vf 0 queue 0 Signed-off-by: Naveen Mamindlapalli <naveenm@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.
