Subject: [PATCHv2 net-next 0/2] net: erspan: add support for openvswitch 

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.

  net: erspan: use bitfield instead of mask and offset
  openvswitch: add erspan version II support
