Yes I have seen that. It is well explained. But still I cannot formulate the answer to this statement …" if I receive WMM negotiated traffic on a WLAN, and bridge forward it to the same or other WLAN in the same MKT will it still carry that WMM priority? …"

If the priority is maintained in the MKT, then with the default config only priority=0 will use A-PMDU. Could be a performance disaster.
[/quote]That’s always a trade-off between bandwidth and latency. Sometimes you have to scarify one or the other for a specific traffic.
I know this trade-off. But the implementation in MKT is not clear to me. Is the on/off selection per priority of the a-PMDU a selection between " 64 MSDU and 64 bit blockACK" or “no A-PMDU”? Or is this moderated or adaptive aggregation. Can we see what it does? … http://forum.mikrotik.com/t/how-to-get-rid-of-slow-wifi-can-it-be-done/139640/1 (with links towards adaptive frame aggregation tests). Exemples of adaptive frame aggregation show typically 2 MSDU in one A-MSDU, 16 A-MSDU in one A-PMDU, but fluctuating like the MCS rate selection.
