8 years agomlx5: refactor Rx code for the new verbs RSS API
Adrien Mazarguil [Fri, 30 Oct 2015 18:55:06 +0000 (19:55 +0100)]
mlx5: refactor Rx code for the new verbs RSS API

The new Verbs RSS API is lower-level than the previous one and much more
flexible but requires RX queues to use Work Queues (WQs) internally instead
of Queue Pairs (QPs), which are grouped in an indirection table used by a
new kind of hash RX QPs.

Hash RX QPs and the indirection table together replace the parent RSS QP
while WQs are mostly similar to child QPs.

RSS hash key is not configurable yet.

Summary of changes:

- Individual DPDK RX queues do not store flow properties anymore, this info
  is now part of the hash RX queues.
- All functions affecting the parent queue when RSS is enabled or the basic
  queues otherwise are modified to affect hash RX queues instead.
- Hash RX queues are also used when a single DPDK RX queue is configured (no
  RSS) to remove that special case.
- Hash RX queues and indirection table are created/destroyed when device
  is started/stopped in addition to create/destroy flows.
- Contrary to QPs, WQs are moved to the "ready" state before posting RX
  buffers, otherwise they are ignored.
- Resource domain information is added to WQs for better performance.
- CQs are not resized anymore when switching between non-SG and SG modes as
  it does not work correctly with WQs. Use the largest possible size
  instead, since CQ size does not have to be the same as the number of
  elements in the RX queue. This also applies to the maximum number of
  outstanding WRs in a WQ (max_recv_wr).
