Codel not applying after 4gb/s ?

[Poli]

I am playing around with codel.
I want to limit a certain Connection to max 10gb/s (I know it's obvious since it's nearly the max capacity of a PfSense) but hear me out.

Basically.
If I set my Limiter to max 100mbits it works fine

Now If I set it to 10gb/s it is still limited to the original 100mbps.

Alright that's weird right?

Now if I set it to 4 gb/s

Youcan clearly see here, that the limit is now unlocked. But why? Why don't 10000 mbits works?
I tried 9999 doesn't work as well.

I tried with bits too it doesn't work.
I tried also to put a longer queue it doesn't work.
And lastly I tried to disable ECN it doesn't work.

It's so weird, why would it work with 4 but not with 5,6,7,8,9 or even 10gb/s?

Thanks in advance for your help!

@Poli Oh I founded that, so BSD still didn't fix it ? https://redmine.pfsense.org/issues/12661

I guess the fix was an upgrade from 2gb/s to 4gb/s why so low? https://reviews.freebsd.org/D31582
