selftests/bpf: Add more test cases for LPM trie
Add more test cases for LPM trie in test_maps:
1) test_lpm_trie_update_flags
It constructs various use cases for BPF_EXIST and BPF_NOEXIST and check
selftests/bpf: Add more test cases for LPM trie
Add more test cases for LPM trie in test_maps:
1) test_lpm_trie_update_flags
It constructs various use cases for BPF_EXIST and BPF_NOEXIST and check
whether the return value of update operation is expected.
2) test_lpm_trie_update_full_maps
It tests the update operations on a full LPM trie map. Adding new node
will fail and overwriting the value of existed node will succeed.
3) test_lpm_trie_iterate_strs and test_lpm_trie_iterate_ints
There two test cases test whether the iteration through get_next_key is
sorted and expected. These two test cases delete the minimal key after
each iteration and check whether next iteration returns the second
minimal key. The only difference between these two test cases is the
former one saves strings in the LPM trie and the latter saves integers.
Without the fix of get_next_key, these two cases will fail as shown
below:
test_lpm_trie_iterate_strs(1091):FAIL:iterate #2 got abc exp abS
test_lpm_trie_iterate_ints(1142):FAIL:iterate #1 got 0x2 exp 0x1

selftests/bpf: Move test_lpm_map.c to map_tests
Move test_lpm_map.c to map_tests/ to include LPM trie test cases in
regular test_maps run. Most code remains unchanged, including the use of
assert().
selftests/bpf: Move test_lpm_map.c to map_tests
Move test_lpm_map.c to map_tests/ to include LPM trie test cases in
regular test_maps run. Most code remains unchanged, including the use of
assert(). Only reduce n_lookups from 64K to 512, which decreases
test_lpm_map runtime from 37s to 0.7s.
