The first patch refactors the originally erspan header definitions. Originally, the erspan fields are defined as a group into a __be16 field, and use mask and offset to access each field. This is more costly due to calling ntohs/htons and error-prone. The first patch changes it to use bitfields. The second patch introduces the new OVS tunnel key attribute to program both v1 and v2 erspan tunnel for openvswitch.
