Help me update my HFSC shaper scripts for fw4/nftables

You should be able to disable ACK limiting if you don't need it by:

ACKRATE=""

Or by commenting it out:

#ACKRATE="$(($UPRATE * 5 / 100))" # auto mode - or set manually

However, I discovered a bug that prevented it from being disabled. Pushed a fix to my github repo...

Generally speaking, I have been overestimating the ACKRATE by using 5% of the total upload bandwidth.

Look at this post from @moeller0:

1/40 is 2,5 %, so my guess was that with a high upload bandwidth, not much traffic would land in the ACK limiting rules.

I don't know. I guess first we would need to determine if there is an issue with the current settings.
