That is a good point! We talk about as we may know every use case of
Linux. But this is not true at all. One of my customer for example operates
the Linux network stack functionality on top of a proprietary MAC/Driver
where the current packet queue characteristic is just fine. The
time-drop-approach is unsuitable because the bandwidth can vary in a small
amount of time over a great range (0 till max. bandwidth). A sufficient
buffering shows up superior in this environment (only IPv{4,6}/UDP).
