As dst_cookie is used in fast path sctp_transport_dst_check.
Before:
struct sctp_transport {
struct list_head transports; /* 0 16 */
atomic_t refcnt; /* 16 4 */
__u32 dead:1; /* 20:31 4 */
__u32 rto_pending:1; /* 20:30 4 */
__u32 hb_sent:1; /* 20:29 4 */
__u32 pmtu_pending:1; /* 20:28 4 */
/* XXX 28 bits hole, try to pack */
__u32 sack_generation; /* 24 4 */
/* XXX 4 bytes hole, try to pack */
struct flowi fl; /* 32 64 */
/* --- cacheline 1 boundary (64 bytes) was 32 bytes ago --- */
union sctp_addr ipaddr; /* 96 28 */
After:
struct sctp_transport {
struct list_head transports; /* 0 16 */
atomic_t refcnt; /* 16 4 */
__u32 dead:1; /* 20:31 4 */
__u32 rto_pending:1; /* 20:30 4 */
__u32 hb_sent:1; /* 20:29 4 */
__u32 pmtu_pending:1; /* 20:28 4 */
/* XXX 28 bits hole, try to pack */
__u32 sack_generation; /* 24 4 */
u32 dst_cookie; /* 28 4 */
struct flowi fl; /* 32 64 */
/* --- cacheline 1 boundary (64 bytes) was 32 bytes ago --- */
union sctp_addr ipaddr; /* 96 28 */
