Jakub Kicinski says: ==================== xdp: use netlink extended ACK reporting This series is an attempt to make XDP more user friendly by enabling exploiting the recently added netlink extended ACK reporting to carry messages to user space. David Ahern's iproute2 ext ack patches for ip link are sufficient to show the errors like this: Error: nfp: MTU too large w/ XDP enabled Where the message is coming directly from the driver. There could still be a bit of a leap for a complete novice from the message above to the right settings, but it's a big improvement over the standard "Invalid argument" message. v1/non-rfc: - add a separate macro in patch 1; - add KBUILD_MODNAME as part of the message (Daniel); - don't print the error to logs in patch 1. ==================== 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.
