In order to improve performance of flow counter stats query loop that traverses all configured flow counters, replace rb_tree with double-linked list. This change improves performance of traversing flow counters by removing the tree traversal. (profiling data showed that call to rb_next was most top CPU consumer) However, lookup of flow flow counter in list becomes linear, instead of logarithmic. This problem is fixed by next patch in series, which adds idr for fast lookup. Idr is to be used because it is not an intrusive data structure and doesn't require adding any new members to struct mlx5_fc, which allows its control data part to stay <= 1 cache line in size.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
