Currently, when interface is being brought down and
i40e_vsi_stop_rings() is called, i40e_pf_rxq_wait() is called two times,
which is wrong. To showcase this scenario, simplified call stack looks
as follows:
i40e_vsi_stop_rings()
i40e_control wait rx_q()
i40e_control_rx_q()
i40e_pf_rxq_wait()
i40e_vsi_wait_queues_disabled()
i40e_pf_rxq_wait() // redundant call
To fix this, let us s/i40e_control_wait_rx_q/i40e_control_rx_q within
i40e_vsi_stop_rings().

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.
