Hi Folks,

I'm getting this message after the upgrade from linux 4.18 
to 4.19

root@Calimero:~# tc qdisc add dev eth0 root handle 1:0 hfsc default 1
Error: Attribute failed policy validation.

root@Calimero:~# lsmod  |  grep hfsc
sch_hfsc               24576  0

root@Calimero:~# tc -V
tc utility, iproute2-ss181023

Am I doing anything wrong?
