Unlike ethtool stats, get_stats ndo provides information cached by update stats work that is running in the background without updating them explicitly. We cannot update all counters inside the ndo because some updates require firmware commands that cannot be performed under a spinlock. update_stats work does not need to update ALL counters, since only some of them are needed by ndo_get_stats. This patch will allow for a minimal run of update_stats using an extra parameter which will update necessary counters only and cut 13 firmware commands in each iteration of the work. Work duration previous to this patch: ~4200us. Work duration after this patch: ~700us (17% of the original time).

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.
