The structure 'mlxsw_pci_queue' stores several counters which were consumed
via debugfs. Since commit 9a32562bec ("mlxsw: Remove debugfs interface"),
these counters are not used. Remove them. This makes the 'union u' and
'struct eq' redundant. Maintain 'struct cq' as it will be extended later.
Replace increasing 'q->u.eq.ev_other_count' with WARN_ON_ONCE(), as it is
used in an unreasonable case of receiving event in EQ which is not EQ0 or
EQ1. When the queues are initialized, we check number of event queues and
fail with the print "Unsupported number of queues" in case that the driver
tries to initialize more than two 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.
