net: erspan: introduce erspan v2 for ip_gre
The patch adds support for erspan version 2. Not all features are
supported in this patch. The SGT (security group tag), GRA (timestamp
granularity), FT (frame type) are set to fixed value. Only hardware
ID and direction are configurable. Optional subheader is also not
supported.
