	Since, the new syntax of BTF-defined map has been introduced, the syntax for using maps under samples directory are mixed up. For example, some are already using the new syntax, and some are using existing syntax by calling them as 'legacy'. As stated at commit abd29c931459 ("libbpf: allow specifying map definitions using BTF"), the BTF-defined map has more compatablility with extending supported map definition features. The commit doesn't replace all of the map to new BTF-defined map, because some of the samples still use bpf_load instead of libbpf, which can't properly create BTF-defined map. This will only updates the samples which uses libbpf API for loading bpf program. (ex. bpf_prog_load_xattr) Signed-off-by: Daniel T.

2016-07-20	bpf: make xdp sample variable names more meaningful	Brenden Blanco
	The naming choice of index is not terribly descriptive, and dropcnt is in fact incorrect for xdp2. Pick better names for these: ipproto and rxcnt. Signed-off-by: Brenden Blanco <bblanco@plumgrid.com> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-07-19	bpf: add sample for xdp forwarding and rewrite	Brenden Blanco
	Add a sample that rewrites and forwards packets out on the same interface. Observed single core forwarding performance of ~10Mpps. Since the mlx4 driver under test recycles every single packet page, the perf output shows almost exclusively just the ring management and bpf program work. Slowdowns are likely occurring due to cache misses. Signed-off-by: Brenden Blanco <bblanco@plumgrid.com> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.
