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.
