bpftool: Show also the name of type BPF_OBJ_LINK
For example, /sys/fs/bpf/maps.debug is a BPF link. When you run `bpftool map show` to show it: Before: $ bpftool map show pinned /sys/fs/bpf/maps.debug Error: incorrect object type: unknown After: $ bpftool map show pinned /sys/fs/bpf/maps.debug Error: incorrect object type: link Signed-off-by: Yafang Shao <laoar.shao@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Reviewed-by: Quentin Monnet <quentin@isovalent.com> Link: https://lore.kernel.org/bpf/20220629154832.56986-5-laoar.shao@gmail.com
