be2net: move txcp field in be_tx_obj to eliminate holes in the struct
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 */
...
};
