Added police action for ingress TC flower hardware offload. With this rate limiting can be done per flow. Since rate limiting is tied to RQs in hardware the number of TC flower filters with action as police is limited to number of receive queues of the interface. Both bps and pps modes are supported. Examples to rate limit a flow: $ ethtool -K eth0 hw-tc-offload on $ tc qdisc add dev eth0 ingress $ tc filter add dev eth0 parent ffff: protocol ip \ flower ip_proto udp dst_port 80 action \ police rate 100Mbit burst 32Kbit $ tc filter add dev eth0 parent ffff: \ protocol ip flower dst_mac 5e:b2:34:ee:29:49 \ action police pkts_rate 5000 pkts_burst 2048 Signed-off-by: Subbaraya Sundeep <sbhatta@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.
