[PATCH net-next 0/9] mlx4: order-0 allocations and page recycling

As mentioned half a year ago, we better switch mlx4 driver to order-0
allocations and page recycling.

This reduces vulnerability surface thanks to better skb->truesize tracking
and provides better performance in most cases.

Worth noting this patch series deletes more than 100 lines of code ;)

Eric Dumazet (9):
  mlx4: use __skb_fill_page_desc()
  mlx4: dma_dir is a mlx4_en_priv attribute
  mlx4: remove order field from mlx4_en_frag_info
  mlx4: get rid of frag_prefix_size
  mlx4: rx_headroom is a per port attribute
  mlx4: reduce rx ring page_cache size
  mlx4: removal of frag_sizes[]
  mlx4: use order-0 pages for RX
  mlx4: add page recycling in receive path
