Petr Machata c19cdd72b3 mlxsw: spectrum_cnt: Reorder counter pools
[ Upstream commit 4b7a632ac4e7101ceefee8484d5c2ca505d347b3 ]

Both RIF and ACL flow counters use a 24-bit SW-managed counter address to
communicate which counter they want to bind.

In a number of Spectrum FW releases, binding a RIF counter is broken and
slices the counter index to 16 bits. As a result, on Spectrum-2 and above,
no more than about 410 RIF counters can be effectively used. This
translates to 205 netdevices for which L3 HW stats can be enabled. (This
does not happen on Spectrum-1, because there are fewer counters available
overall and the counter index never exceeds 16 bits.)

Binding counters to ACLs does not have this issue. Therefore reorder the
counter allocation scheme so that RIF counters come first and therefore get
lower indices that are below the 16-bit barrier.

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.
