While the Rx queue fullness reaches the LWM limit, the driver catches
an HW event and invokes the user callback.

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(Limit Watermark) event.

00Mbps.
To disable lwm_triggered and configure a shaper of 5Gbps on port 1:
testpmd> set port 1 host_shaper lwm_triggered 0 rate 50
Add sample code to handle rxq LWM event, it delays a while so that rxq
empties, then disables host shaper and rearms LWM event.

the PMD private logic from testpmd common code, but still give a chance to call
private APIs in testpmd?
