SPDX-License-Identifier: GPL-2.0 4 XDP RX Metadata 7 This document describes how an eXpress Data Path (XDP) program can access 8 hardware metadata related to a packet using a set of helper functions, 9 and how it can pass that metadata on to other consumers. 14 XDP has access to a set of kfuncs to manipulate the metadata in an XDP frame. 15 Every device driver that wishes to expose additional packet metadata can 16 implement these kfuncs. The set of kfuncs is declared in ``include/net/xdp.h`` 20 metadata is supported, this set will grow: 22 .. kernel-doc:: net/core/xdp.c [all …]
