in the changelog of V4.50 at page 17 is some news about BWM:
[ENHANCEMENT][BWM] Let TCP ack packets can be managed by BWM
function. Add CLI command to enable/disable this enhancement.
(eITS#180700033, 200200602)

But I don't find a description or a command in the CLI reference guide.
@Zyxel: can you provide some information?

    configure terminal
    Router(config)# bwm control-tcp-ack

    By default (for some reason) when you download small ack packets are sent back bypassing the BWN but with bwm control-tcp-ack they are not.

    This is useful when you set a egress limit and don't want to go over the limit much were as without the  control-tcp-ack when doing a download and upload at the same time you go over the limit.
