Subject: [PATCH bpf-next 0/6] bpftool: support queue and stack

This patch series add support for queue/stack manipulations.

It goes like this:

#1 and #2 add support for queue/stack in existing 'update' and 'lookup'
commands by permitting empty keys.
#3 make sure we don't print empty keys for queue/stack.
#4 adds peek command, it's essentially an alias for 'lookup'.
#5 adds push/enqueue commands, an alias to 'update'.
#6 adds pop/dequeue commands that use bpf_map_lookup_and_delete_elem.

(Not sure whether it makes sense to have push/enqueue + pop/dequeue or
just have push/pop for both stack/queue, comments are welcome).

Stanislav Fomichev (6):
  bpftool: make key and value optional in update command
  bpftool: make key optional in lookup command
  bpftool: don't print empty key/value for maps
  bpftool: add peek command
  bpftool: add push and enqueue commands
  bpftool: add pop and dequeue commands
