Orabug: 29475071

Before patch:
struct be_tx_obj {
        u32                        db_offset;            /*     0     4 */

        /* XXX 4 bytes hole, try to pack */

        struct be_queue_info       q;                    /*     8    56 */
        /* --- cacheline 1 boundary (64 bytes) --- */
        struct be_queue_info       cq;                   /*    64    56 */
        struct be_tx_compl_info    txcp;                 /*   120     4 */

        /* XXX 4 bytes hole, try to pack */

        /* --- cacheline 2 boundary (128 bytes) --- */
        struct sk_buff *           sent_skb_list[2048];  /*   128 16384 */
        ...
}:

After patch:
struct be_tx_obj {
        u32                        db_offset;            /*     0     4 */
        struct be_tx_compl_info    txcp;                 /*     4     4 */
        struct be_queue_info       q;                    /*     8    56 */
        /* --- cacheline 1 boundary (64 bytes) --- */
        struct be_queue_info       cq;                   /*    64    56 */
        struct sk_buff *           sent_skb_list[2048];  /*   120 16384 */
