mlx5e_activate_priv_channels() and mlx5e_deactivate_priv_channels() start and stop all netdev TX queues. This commit removes the unneeded call to netif_tx_stop_all_queues and adds explanatory comments why these operations are needed. netif_tx_disable() does the same thing that netif_tx_stop_all_queues(), but taking the TX lock, thus guaranteeing that ndo_start_xmit is not running after return. That means that the netif_tx_stop_all_queues() call is not really necessary. The comments are improved: the TX watchdog timeout explanation is moved to the start stage where it really belongs (it used to be in both places, but was lost during some old refactoring) and rephrased in more details; the explanation for stopping all TX queues is added.

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.
