ICM device memory is used for writing steering rules (STEs) to the NIC. An ICM memory pool allocator was implemented to manage the required memory. The pool consists of buckets, a bucket per chunk size. Once a bucket is empty we will cut a row of memory from the latest allocated MR, if the MR size is not sufficient we will allocate a new MR. HW design requires that chunks memory address should be aligned to the chunk size, this is the reason for managing the MR with row size that insures memory alignment. Current design is greedy in memory but provides quick allocation times in steady state.

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.
