It is being used indirectly, e.g. dpaa_sec.h usages it for ip address description preparation for the hardware.
struct ipsec_encap_pdb encap_pdb;
union {
struct ip ip4_hdr;
struct rte_ipv6_hdr ip6_hdr;
};
We need to change it, however in the interim, I will like to add "-Wno-gnu-variable-sized-type-not-at-end" for both caam_jr and dpaa_sec to avoid this warning.
