2023-08-24samples/bpf: Remove the xdp_redirect* utilitiesToke Høiland-Jørgensen1-539/+0
These utilities have all been ported to xdp-tools as functions of the xdp-bench utility. The four different utilities in samples are incorporated as separate subcommands to xdp-bench, with most of the command line parameters left intact, except that mandatory arguments are always positional in xdp-bench. For full usage details see the --help output of each command, or the xdp-bench man page. Some examples of how to convert usage to xdp-bench are: xdp_redirect eth0 eth1 --> xdp-bench redirect eth0 eth1 xdp_redirect_map eth0 eth1 --> xdp-bench redirect-map eth0 eth1 xdp_redirect_map_multi eth0 eth1 eth2 eth3 --> xdp-bench redirect-multi eth0 eth1 eth2 eth3 xdp_redirect_cpu -d eth0 -c 0 -c 1 --> xdp-bench redirect-cpu -c 0 -c 1 eth0 xdp_redirect_cpu -d eth0 -c 0 -c 1 -r eth1 --> xdp-bench redirect-cpu -c 0 -c 1 eth0 -r redirect -D eth1 Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> Link: https://lore.kernel.org/r/20230824102255.1561885-3-toke@redhat.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2021-08-24samples: bpf: Convert xdp_redirect_cpu_kern.o to XDP samples helperKumar Kartikeya Dwivedi1-0/+541
Similar to xdp_monitor_kern, a lot of these BPF programs have been reimplemented properly consolidating missing features from other XDP samples. Hence, drop the unneeded code and rename to .bpf.c suffix.
