pnat: add support to wildcard IP Protocol field if not specified
- add pnat_binding_add_v2 which explicitly requires match mask to set to PNAT_PROTO if we want to match on IP Protocol - fix pnat_binding_add backward compatibility i.e. no need to set match mast to PNAT_PROTO Type: improvement Signed-off-by: Fahad Naeem <fahadnaeemkhan@gmail.com> Change-Id: I5a23244be55b7d4c10552c555881527a4b2f325f
