mlx4 uses a bounce buffer in TX whenever the tx descriptors
wrap around the right edge of the ring.

Size of this bounce buffer was hard coded and can be
increased if/when needed.

v2: roundup MLX4_TX_BOUNCE_BUFFER_SIZE (Tariq)

Eric Dumazet (3):
  net/mlx4: rename two constants
  net/mlx4: MLX4_TX_BOUNCE_BUFFER_SIZE depends on MAX_SKB_FRAGS
  net/mlx4: small optimization in mlx4_en_xmit()
