[PATCH bpf-next 0/4] libbpf: streamline netlink-based XDP APIs

[Andrii Nakryiko <andrii@kernel.org>]

Revamp existing low-level XDP APIs provided by libbpf to follow more
consistent naming (new APIs follow bpf_tc_xxx() approach where it makes
sense) and be extensible without ABI breakages (OPTS-based). See patch #1 for
details, remaining patches switch bpftool, selftests/bpf and samples/bpf to
new APIs.

Andrii Nakryiko (4):
  libbpf: streamline low-level XDP APIs
  bpftool: use new API for attaching XDP program
  selftests/bpf: switch to new libbpf XDP APIs
  samples/bpf: adapt samples/bpf to bpf_xdp_xxx() APIs
