Saeed Mahameed 8772cc499b net/mlx5e: Fix use-after-free in mlx5e_stats_grp_sw_update_stats 
We need to sync page pool stats only for active channels. Reading ethtool
stats on a down netdev or a netdev with modified number of channels will
result in a user-after-free, trying to access page pools that are freed
already.

BUG: KASAN: use-after-free in mlx5e_stats_grp_sw_update_stats+0x465/0xf80
Read of size 8 at addr ffff888004835e40 by task ethtool/720

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.
