In struct rte_security_ipsec_sa_options, for every new option added, there is an ABI breakage, to avoid, a reserved_opts bitfield is added to for the remaining bits available in the structure. Now for every new sa option, these reserved_opts can be reduced and new option can be added. A corresponding exception is also added in devtools/libabigail.abignore
