In kernel datapath of Open vSwitch, there are only 1024 buckets of meter in one datapath. If installing more than 1024 (e.g. 8192) meters, it may lead to the performance drop. But in some case, for example, Open vSwitch used as edge gateway, there should be 20K at least, where meters used for IP address bandwidth limitation. [Open vSwitch userspace datapath has this issue too.] For more scalable meter, this patch use meter array instead of hash tables, and expand/shrink the array when necessary. So we can install more meters than before in the datapath. Introducing the struct *dp_meter_instance, it's easy to expand meter though changing the *ti point in the struct *dp_meter_table.

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.
