I've just tried and the results are kind of the opposite of what I
would expect. Here are the values so maybe you'll have a different
understanding:

From --pacing-timer 1 to 100000 (should be microseconds IIUC), results
are the same. And then, increasing the period decreases the drop rate:

# iperf3 -c 192.168.1.1 -u -b1M --pacing-timer 1000
[  5]   0.00-10.04  sec   604 KBytes   493 Kbits/sec  0.062 ms  437/864 (51%)  receiver

PHY statistics remain empty:

Interrupts work as expected on the MAC side (I added traces in the IRQ
handler to see how it was behaving):

Well, isn't it kind of the opposite? If we flood the interface it works
better than when we pace the traffic (that's what I see whenever I
reduce the throughput or when I enlarge the iperf timer).

I'm also doubtful about the fact that receiving full speed traffic makes
the uplink stable.

Thanks,
