Hangbin Liu 71c7c1fb4f examples/bpf: add bpf examples with BTF defined maps Users should try use the new BTF defined maps instead of struct bpf_elf_map defined maps. The tail call examples are not added yet as libbpf doesn't currently support declaratively populating tail call maps.

README

eBPF toy code examples (running in kernel) to familiarize yourself
with syntax and features:

- BTF defined map examples
 - bpf_graft.c		-> Demo on altering runtime behaviour
 - bpf_shared.c 	-> Ingress/egress map sharing example
 - bpf_map_in_map.c	-> Using map in map example

- legacy struct bpf_elf_map defined map examples
 - legacy/bpf_shared.c		-> Ingress/egress map sharing example
 - legacy/bpf_tailcall.c	-> Using tail call chains
 - legacy/bpf_cyclic.c		-> Simple cycle as tail calls
 - legacy/bpf_graft.c		-> Demo on altering runtime behaviour
 - legacy/bpf_map_in_map.c	-> Using map in map example

Note: Users should use new BTF way to defined the maps, the examples
in legacy folder which is using struct bpf_elf_map defined maps is not
recommanded.
