Merge branch 'mlx5e-order-0'
Tariq Toukan says: ==================== mlx5e Order-0 pages for Striding RQ In this series, we refactor our Striding RQ receive-flow to always use fragmented WQEs (Work Queue Elements) using order-0 pages, omitting the flow that allocates and splits high-order pages which would fragment and deplete high-order pages in the system. The first patch gives a slight degradation, but opens the opportunity to using a simple page-cache mechanism of a fair size. The page-cache, implemented in patch 3, not only closes the performance gap but even gives a gain. In patch 2 we re-organize the code to better manage the calls for alloc/de-alloc pages in the RX flow. Series generated against net-next commit: bed806cb266e "Merge branch 'mlxsw-ethtool'" ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
