Vlad Buslov 5a7e5bcb66 net/mlx5e: Extend tc flow struct with reference counter
With new classifier type that doesn't require rtnl lock, following
invariant holds:
 - Filter with specified cookie created only once.
 - Filter with specified cookie deleted only once.
 - Stats updates can be performed in parallel to each other.

Extend tc flow with rcu and reference counter. To protect from concurrent
delete, get reference to tc flow when:
 - Reading flow stats.
 - Accessing flow in neigh update handler.
 - Accessing flow in neigh update used value handler.

Only free flow when reference counter reached zero. Modify flow cleanup to
account for flows that could be not fully initialized by checking if flow
is actually in the list of corresponding mod_hdr, hairpin and encap
entries. Don't cleanup flow directly in case of error to allow concurrent
neigh update (neigh update will be modified to always take reference to
flow when using it).

README

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.
