From b4b8faa1ded7a3bb34db374c692a51cea29f9080 Mon Sep 17 00:00:00 2001 From: Magnus Karlsson Date: Wed, 2 May 2018 13:01:36 +0200 Subject: samples/bpf: sample application and documentation for AF_XDP sockets MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a sample application for AF_XDP sockets. The application supports three different modes of operation: rxdrop, txonly and l2fwd. To show-case a simple round-robin load-balancing between a set of sockets in an xskmap, set the RR_LB compile time define option to 1 in "xdpsock.h". v2: The entries variable was calculated twice in {umem,xq}_nb_avail.
