i40e_print_link_message() is intended to compare new link state with current link state and print log message only if the new state is different from current state. However in current driver the new state does not get updated when link is going down because of the if condition. When an interface is brought down, vsi->state is set to I40E_VSI_DOWN in i40e_vsi_close() and later i40e_print_link_message() does not get invoked in i40e_link_event due to if condition. Hence link down message doesn't appear when link is going down. The down state is seen later during i40e_open() and old state gets printed. The actual link state doesn't get updated in i40e_close() or i40e_open() but when i40e_handle_link_event is called inside i40e_clean_adminq_subtask. This change allows i40e_print_link_message() to be called when interface is going down and keeps the state information updated.

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.
