The existing net,mac test didn't cover the issue recently reported by Nikita Yushchenko, where MAC addresses wouldn't match if given as first field of a concatenated set with AVX2 and 8-bit groups, because there's a different code path covering the lookup of six 8-bit groups (MAC addresses) if that's the first field. Add a similar mac,net test, with MAC address and IPv4 address swapped in the set specification.
