I checked again, and my WDR4900 with same setup doesn't lose packets
either. Even at 99% sirq, no packets are lost.
WRT1200AC starts to lose packets at 500 megabit/s SQM around MSS 300 and
lower. If I turn off gso, tso and gro, I have to go to MSS 600 and above
to avoid packet loss.
Does flent check for packet loss at all? Perhaps it's something to look
into, because with ECN we really don't want to see any packets lost and
this might be good to include test results for.
