Florian Fainelli says: ==================== net: Broadcom drivers coalescing fixes Following Tal's review of the adaptive RX/TX coalescing feature added to the SYSTEMPORT and GENET driver a number of things showed up: - adaptive TX coalescing is not actually a good idea with the current way the estimator will program the ring, this results in a higher CPU load, NAPI on TX already does a reasonably good job at maintaining the interrupt count low - both SYSTEMPORT and GENET would suffer from the same issues while configuring coalescing parameters where the values would just not be applied correctly based on user settings, so we fix that too Tal, thanks again for your feedback, I would appreciate if you could review that the new behavior appears to be implemented correctly. Thanks! Changes in v2: - added Tal's reviewed-by to the first patch - split DIM initialization from coalescing parameters initialization - avoid duplicating the same code in bcmgenet_set_coalesce() when configuring RX rings - fixed the condition where default DIM parameters would be applied when adaptive RX coalescing would be enabled, do this only if it was disabled before ==================== 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.
