Jakub Kicinski says: ==================== nfp: get_phys_port_name for representors and SR-IOV reorder This series starts by making the error message if FW cannot be located easier to understand. Then I move some functions from PCI probe files into library code (nfpcore) where they belong, and remove one function which is never used. Next few patches equip representors with nfp_port structure and make their NDOs fully shared (not defined in apps), thanks to which we can easily determine which netdevs are NFP's by comparing the NDO pointers. 10th patch makes use of the shared NDOs and nfp_ports to deliver netdev-type independent .ndo_get_phys_port_name() implementation. Patches 11 and 12 reorder the nfp_app SR-IOV callbacks with enabling SR-IOV VFs. Unfortunately due to how PCI subsystem works we can't guarantee being able to disable SR-IOV at exit or that it will be disabled when we first probe... We must therefore make sure FW is able to deal with being loaded while SR-IOV is already on. Patch 13 fixes potential deadlock when enabling SR-IOV happens at the same time as port state refresh. Note that this can't happen at this point, since Flower doesn't refresh ports... but lockdep doesn't know about such details and we will have to deal with this sooner or later anyway. Last but not least a new Kconfig is added to make sure those who don't care about flower offloads have a way of not including the code in their kernels. Thanks to nfp_app separation this costs us a single ifdef and excluding flower files from the build. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

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.
