Flood profiles have been used prior to CFF support for NVE underlay. Like
is the case with FID flooding, an NVE profile describes at which offset a
datum is located given traffic type. mlxsw currently only ever uses one KVD
entry for NVE lookup, i.e. regardless of traffic type, the offset is always
zero. To be able to describe this, add a traffic type enumerator describing
"any traffic type".
