Previously Q-counters data was being allocated over the PF for all of
the available vports, however that isn't necessary.
Since each VF or SF has a Q-counter allocated for itself.
So we only need to allocate two counters data structures, one for the
device counters, and one for all the other vports to expose the
representors, since they only need to read from it in order to
determine mainly counters numbers and names, so they can all share.
This in turn also solves a bug we previously had where we couldn't
switch the device to switchdev mode when there were more than 128 SF/VFs
configured, since that is the maximum amount of Q-counters available for
a single port

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.
