This patch adds NSH header structures and helpers for NSH GSO support and Open vSwitch NSH support. [1] https://datatracker.ietf.org/doc/draft-ietf-sfc-nsh/ [Jiri: added nsh_hdr() helper and renamed the header struct to "struct nshhdr" to match the usual pattern. Removed packet type defines, these are now shared with VXLAN-GPE.] Signed-off-by: Yi Yang <yi.y.yang@intel.com> Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S.
