This series from Tariq includes micro data path optimization for mlx5e netdevice driver. Mainly Tariq introduces the following changes to NAPI and RX handling path of the driver: - RX ring structure reorganizing - Trivial code refactoring and optimization - NAPI busy-poll for when fast UMR is in progress - Non-atomic state operations in NAPI context - Remove unnecessary fields from fast path structures - page-cache micro optimization - Rely on NAPI to avoid missing an IRQ for RX/TX shared NAPI contexts - Stop NAPI when irq changes affinity - Distribute RSS table among all RX rings Thanks, Saeed. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJZq3r/AAoJEEg/ir3gV/o+ZtwIAK6LcyUxNSa+Q8a7+57EIQgj xwA76EG1x5MskZ30QRJpZG6VP6C2WEOtG0/WDi6yfEzZh5J0+clqVv1cHVIJIFhC vB+0FCl8GIlTE/VMpRFqFTZapz6/BWCWNQEW3a1raHb026cpeRzq7c+g1x4lKXx5 RN0QhOd/G+yUz6A+xt6GCRlHsIkvFpigL90rhfQqcvg/T8QepxZ1trJiytpu2J51 OhEtnl9mIapgj0Z9nQMMKV+BnLSaJxlJ2j5xGWa5x8zuySrGv/P26TYDsAvYp8pV +f9OgISoQr7d2mWyus3IYSi31F3AkbGE01K3vBQTXpyd8pdEqv5bzXXWJtQASeQ= =dmvv -----END PGP SIGNATURE----- Merge tag 'mlx5-updates-2017-09-03' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2017-09-03 This series from Tariq includes micro data path optimization for mlx5e netdevice driver.

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.
