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. Signed-off-by: William Tu <u9012063@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
