Florian Fainelli says: ==================== net: broadcom: Adaptive interrupt coalescing This patch series adds adaptive interrupt coalescing for the Gigabit Ethernet drivers SYSTEMPORT and GENET. This really helps lower the interrupt count and system load, as measured by vmstat for a Gigabit TCP RX session: SYSTEMPORT: without: 1 0 0 192188 0 25472 0 0 0 0 122100 38870 1 42 57 0 0 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.0 sec 1.03 GBytes 884 Mbits/sec with: 1 0 0 192288 0 25468 0 0 0 0 58806 44401 0 100 0 0 0 [ 5] 0.0-10.0 sec 1.04 GBytes 888 Mbits/sec GENET: without: 1 0 0 1170404 0 25420 0 0 0 0 130785 63402 2 85 12 0 0 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.0 sec 1.04 GBytes 888 Mbits/sec with: 1 0 0 1170560 0 25420 0 0 0 0 50610 48477 0 100 0 0 0 [ 5] 0.0-10.0 sec 1.05 GBytes 899 Mbits/sec Please look at the implementation and let me know if you see any problems, this was largely inspired by bnxt_en. ==================== Signed-off-by: David S.

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.
