LWM(limit watermark) is per RX queue attribute, when RX queue fullness reach
the LWM limit, HW sends an event to dpdk application.
Host shaper can configure shaper rate and lwm-triggered for a host port.
The shaper limits the rate of traffic from host port to wire port.
If lwm-triggered is enabled, a 100Mbps shaper is enabled automatically
when one of the host port's Rx queues receives LWM event.

These two features can combine to control traffic from host port to wire port.
The work flow is configure LWM to RX queue and enable lwm-triggered flag in
host shaper, after receiving LWM event, delay a while until RX queue is empty
, then disable the shaper. We recycle this work flow to reduce RX queue drops.

Spike Du (6):
  net/mlx5: add LWM support for Rxq
  common/mlx5: share interrupt management
  net/mlx5: add LWM event handling support
  net/mlx5: add private API to configure Rxq LWM
  net/mlx5: add private API to config host port shaper
  app/testpmd: add LWM and Host Shaper command
