Linux kernel source tree

Fields 'head', 'tail', 'len', 'bah' and 'bal' in iavf_adminq_ring are used to store register offsets. These offsets are initialized and remains constant so there is no need to store them in the iavf_adminq_ring structure. Remove these fields from iavf_adminq_ring and use register offset constants instead. Remove iavf_adminq_init_regs() that originally stores these constants into these fields. Finally improve iavf_check_asq_alive() that assumes that non-zero value of hw->aq.asq.len indicates fully initialized AdminQ send queue. Replace it by check for non-zero value of field hw->aq.asq.count that is non-zero when the sending queue is initialized and is zeroed during shutdown of the queue.

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.
