This state bit was added as a way for DCB to avoid having to wait for the queues to disable when handling LLDP events. The logic for this was burried deep within stop Tx and stop Rx queue code. First, let's rename it so that it does not appear to only affect Tx when infact it modifies both Tx and Rx flow. Second we can move it up into the i40e_stop_rings() function, and we can simply re-use the i40e_stop_rings_no_wait() so that we don't have to bury the implementation as deep into the call stack. An alternative might be to remove the state bit and instead attempt to shut down everything directly in DCP flow. This, however, is not ideal because it creates yet another separate shutdown routine that we'd have to maintain. In the current implementation any changes will be made to both flows.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
