So, given that the DUT is the only real constraint in the network, what
do you expect to see from this setup?

Given that the probably DUT can't forward at Gb/s, and it certainly can't
shape anything, it's gonna drop packets, and it's probably gonna drop them in
Rx, having overrun the Rx-queue (so tail-drop).  If there is too much ram
(bufferbloated), then you'll see different results...
