> If the hardware is constantly receiving unicast or broadcast packets during
> driver load, the device previously counted many GLV_RDPC (VSI dropped
> packets) events during init. This causes confusing dropped packet statistics
> during driver load. The dropped packets counter incrementing does stop once
> the driver finishes loading.
> 
> Avoid this problem by baselining our statistics at the end of driver open instead
> of the end of probe.

> Testing Hints: pktgen or ping flood the DUT, while reloading the driver and
> bringing up the interface (in a script or with networkmanager) and note
> dropped packets with ip -s -s link or ifconfig, after this patch there should be
> none.
