The register 0x07014 is actually the head pointer of CMDQ, and 0x07010 means tail pointer. Current definitions are confusing, so rename them and related variables. The next_to_use of structure hns_roce_v2_cmq_ring has the same semantics as head, merge them into one member. The next_to_clean of structure hns_roce_v2_cmq_ring has the same semantics as tail. After deleting next_to_clean, tail should also be deleted.

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.
