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).
