The label, tc, bos and ttl fields are tested for the first and second labels. For each field, the minimal and maximal values are tested (the former at depth 1 and the later at depth 2). There are also tests for matching the presence of a label stack entry at a given depth. In order to reduce the amount of code, all "lse" subcommands are tested in match_mpls_lse_test(). Action "continue" is used, so that test packets are evaluated by all filters. Then, we can verify if each filter matched the expected number of packets. Some versions of tc-flower produced invalid json output when dumping MPLS filters with depth > 1. Skip the test if tc isn't recent enough.
