This commit optimizes mlx5e_select_queue for HTB and PTP cases by short-cutting some checks, without sacrificing performance of the common non-HTB non-PTP flow. 1. The HTB flow uses the fact that num_tcs == 1 to drop these checks (it's not possible to attach both mqprio and htb as the root qdisc). It's also enough to calculate `txq_ix % num_channels` only once, instead of twice. 2. The PTP flow drops the check for HTB and the second calculation of `txq_ix % num_channels`.

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.
