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).

Removing this structure reduces the size of SG and non-SG RX queue elements
significantly to improve performance.
An nice side effect is that the mbuf pointer is now fully stored in
struct rxq_elt instead of relying on the WR ID data offset hack.

This commit updates mlx5_rx_burst_sp() to use the fast verbs interface for
posting RX buffers just like mlx5_rx_burst(). Doing so avoids a loop in
libmlx5 and an indirect function call through libibverbs.
Note: recv_sg_list() is not implemented in the QP burst API, this commit is
only to prepare transition to the WQ-based API.

A dedicated RX callback is added to handle scattered buffers. For better

On the TX path, scattered buffers are also handled in a separate function.

so PMD driver need to use the Set PHY Config AD command to trigger the PHY
to do the auto-negotiation, after the Tx/Rx pause ability is negotiated,
the F/W will help us to set the related LFC enable/disable registers.
