The low 16 bits of GEM_DCFG6 tell us which queues are enabled in HW. In theory, there could be holes in the bitfield. In practice, the macb driver would fail if there were holes as most loops iterate upon bp->num_queues. Only macb_init() iterated correctly. - Drop bp->queue_mask field. - Error out at probe if a hole is in the queue mask. - Rely upon bp->num_queues for iteration. - As we drop the queue_mask probe local variable, fix RCT. - Compute queue_mask on the fly for TAPRIO using bp->num_queues.

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 reStructuredText 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.
