Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-03-15 This series contains updates to i40e and i40evf only. Aaron fixes an issue on x710 devices where simultaneous read accesses were interfering with each other, so make sure all devices acquire the NVM lock before reads on all devices. Shannon adds Wake On LAN support feature for x722 devices and cleaned up the opcodes so that they are in numerical order. Mitch adds a client interface to the VF driver, in preparation for the upcoming RDMA-capable hardware (and client driver). Cleaned up the client interface in the PF driver, since it was originally over engineered to handle multiple clients on multiple netdevs, but that did not happen and now there will be one client per driver, so apply the "KISS" (Keep It Simple & Stupid) to the i40e client interface. Bumped the number of MAC filters an untrusted VF can create. Jake fixes an issue where a recent refactor of queue pairs accidentally added all remaining vecotrs to the num_lan_msix which can adversely affect performance. Lihong fixes an ethtool issue with x722 devices where "-e" will error out since its EEPROM has a scope limit at offset 0x5B9FFF, so set the EEPROM length to the scope limit. Also fixed an issue where RSS offloading only worked on PF0. Filip cleans up and clarifies code comment so there is no confusion about MAC/VLAN filter initialization routine. Alex adds support for DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING, which improves performance on architectures that implement either one. Harshitha cleans up confusion on flags disabled due to hardware limitation versus featured disabled by the user, so rename auto_disable_flags to hw_disabled_flags to avoid the confusion. v2: Merged patch #1 and #4 in first version to make patch #3 in this series based on feedback from David Miller. ==================== Signed-off-by: David S.

README
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.
