This series makes bpftool able to create outer maps (maps of types
array-of-maps and hash-of-maps). This is done by passing the relevant
inner_map_fd, which we do through a new command-line keyword.

A first patch also cleans up the function related to dumping map elements.

v2:
- v1 was wrongly expected to allow bpftool to dump the content of outer
  maps (already supported). v2 skipped that patch, and instead replaced it
  with a clean-up for the dump_map_elem() function.

Quentin Monnet (2):
  tools: bpftool: clean up function to dump map entry
  tools: bpftool: add "inner_map" to "bpftool map create" outer maps
