When working with frequently modified BPF programs, both the ID and the tag may change. bpftool currently doesn't provide a "stable" way to match such programs. This patchset allows bpftool to match programs and maps by name. When given a tag that matches several programs, bpftool currently only considers the first match. The first patch changes that behavior to either process all matching programs (for the show and dump commands) or error out. The second patch implements program lookup by name, with the same behavior as for tags in case of ambiguity. The last patch implements map lookup by name.
