Use a hole in the structure. We support only Ethernet so far and will add a support for L2-less packets shortly. We could use a bool to indicate whether the Ethernet header is present or not but the approach with the mac_proto field is more generic and occupies the same number of bytes in the struct, while allowing later extensibility. It also makes the code in the next patches more self explaining. It would be nice to use ARPHRD_ constants but those are u16 which would be waste. Thus define our own constants. Another upside of this is that we can overload this new field to also denote whether the flow key is valid. This has the advantage that on refragmentation, we don't have to reparse the packet but can rely on the stored eth.type. This is especially important for the next patches in this series - instead of adding another branch for L2-less packets before calling ovs_fragment, we can just remove all those branches completely.
