And as "host-outbound-traffic" QoS config doesn't work for distributed
PPM protocols (and current info is that this will never be fixed), you
have to configure LACP (and others which you want to use queue-IDs != 7)
to use centralized PPM, and thus LACP PDUs travel RE<->PFE and are prone
to that problem as well.

Shalalala.
