when NDIS framework try to query/set informations NDIS drivers can
return NDIS_STATUS_PENDING.  In this case, it's waiting for 5 secs to
get the response from drivers now.  However, some NDIS drivers can send
the response before NDIS framework gets ready to receive it so we might
always be blocked for 5 secs in current implementation.  NDIS framework
should reset the event before calling NDIS driver's callback not after.
