Jason Wang says: ==================== XDP transmission for tuntap This series tries to implement XDP transmission (ndo_xdp_xmit) for tuntap. Pointer ring was used for queuing both XDP buffers and sk_buff, this is done by encoding the type into lowest bit of the pointer and storin XDP metadata in the headroom of XDP buff. Tests gets 3.05 Mpps when doing xdp_redirect_map from ixgbe to VM (testpmd + virtio-net in guest). This gives us ~20% improvments compared to use skb during redirect. Please review. Changes from V1: - slient warnings - fix typos - add skb mode number in the commit log ==================== 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.
