1. Use struct gre_base_hdr directly in pptp_gre_header instead of duplicated members; 2. Use existing macros like GRE_KEY, GRE_SEQ, and so on instead of duplicated macros defined by PPTP; 3. Add new macros like GRE_IS_ACK/SEQ and so on instead of PPTP_GRE_IS_A/S and so on; Signed-off-by: Gao Feng <fgao@ikuai8.com> Reviewed-by: Philip Prindeville <philipp@redfish-solutions.com> Signed-off-by: David S.
