Thanks for your reply, “done” means the number of packets sent by AMPDU. I did not reproduce the exception log lmac[1] Error, msdu index reach maximum limit, 31. Could you please provide me the topology on your side and the configuration of the parent MikroTik, I'll try to reproduce it, thanks!

OK so done = sent , that makes sense. Now we do sent AMPDU with more MPDU.
Reception max counter seams unrelated (what it should be, but should allow for the max defined in the IEEE802.11ac standard)

Not all lines of the wAP ac device config are relevant. But I know in testing there is never enough detailed information. "nv2" and "nstreme" is not used here. And the multicast-helper=full was because of previous multicast problems/tests.

Only priority is 0, so ampdu setting for 0 is he only one active (no packets for ampdu 1,2,3,4,5 in the data stream)
