Add frag0_dma/frag0_byte_count into mlx4_en_tx_info to avoid a cache line miss in TX completion for frames having one dma element. (We avoid reading back the tx descriptor) Note this could be extended to 2/3 dma elements later, as we have free room in mlx4_en_tx_info Also, mlx4_en_free_tx_desc() no longer accesses skb_shinfo(). We use a new nr_maps fields in mlx4_en_tx_info to avoid 2 or 3 cache misses. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.
