>
> available descriptor threshold(ADT for short) is per RX queue attribute, when
> RX queue available descriptors for HW is below ADT, HW sends an event to
> application.
> Host shaper can configure shaper rate and avail_thresh-triggered for a host
> port.
> The shaper limits the rate of traffic from host port to embedded ARM rx port
> on Nvidia BlueField 2 NIC.
> If avail_thresh-triggered is enabled, a 100Mbps shaper is enabled
> automatically when one of the host port's Rx queues receives available
> descriptor threshold event.
>
> These two features can combine to control traffic from host port to wire port
> for BlueField 2 NIC.
> The traffic flows from host to embedded ARM, then to the physical port.
> The work flow is on the ARM system, configure available descriptor threshold
> to RX queue and enable avail_thresh-triggered flag in host shaper, after
> receiving available descriptor threshold event, delay a while until RX queue is
> empty , then disable the shaper. We recycle this work flow to reduce RX
> queue drops on ARM system.
>
> Add new libethdev API to set available descriptor threshold, add rte event
> RTE_ETH_EVENT_RX_AVAIL_THRESH to handle available descriptor threshold
> event. For host shaper, because it doesn't align to existing DPDK framework
> and is specific to Nvidia NIC, use PMD private API.
>
> For integration with testpmd, put the private cmdline function and available
> descriptor threshold event handler in mlx5 PMD directory by adding a new
> file mlx5_testpmd.c. Follow David Marchand's driver specific commands
> framework to add mlx5 specific commands.
