Option is unparsable

[fernandodiacenco]

Hi there,

On a Debian 10 router with kernel 5.10, I have access to FQ_PIE

If I do for example a tc qdisc replace dev lan0 root fq_pie it works normally

tc qdisc
qdisc fq_pie 8002: dev lan0 root refcnt 5

But if I try changing ANY option, be it quantum, ecn, target, whatever, it returns an error, for example:

tc qdisc replace dev lan0 root fq_pie ecn
Unknown qdisc "fq_pie", hence option "ecn" is unparsable

tc qdisc replace dev lan0 root fq_pie quantum 300
Unknown qdisc "fq_pie", hence option "quantum" is unparsable

I'm confused

Thanks.
