Subject: [PATCH bpf-next 0/2] bpf: implement MAP_GET_NEXT_KEY command for LPM_TRIE map

This patch set implements MAP_GET_NEXT_KEY command for LPM_TRIE map.
This command is really useful for key enumeration, and for key deletion
if what keys in the trie are unknown.

Patch #1 implements the functionality in the kernel and patch #2
adds a test case in tools/testing/selftests/bpf.

  bpf: implement MAP_GET_NEXT_KEY command for LPM_TRIE map
  tools/bpf: add a testcase for MAP_GET_NEXT_KEY command of LPM_TRIE map
