Hi Eric,
Thanks for your series.

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.
The series makes significant change in the RX data-path, that requires
deeper checks, in addition to code review.
We applied your series and started running both our functional and
performance regression.
We will have results by tomorrow morning, and will analyze them during
the day. I'll update about that.
Worth noting this patch series deletes more than 100 lines of code ;)

mlx4: use __skb_fill_page_desc()
mlx4: dma_dir is a mlx4_en_priv attribute

mlx4: rx_headroom is a per port attribute
mlx4: reduce rx ring page_cache size
