2018-05-04samples/bpf: sample application and documentation for AF_XDP socketsMagnus Karlsson1-0/+56
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.
