I'm trying to delete all qdiscs to do "fresh" configuration:
% tc qdisc del dev enp0s25 root
RTNETLINK answers: No such file or directory
But it's there:
% tc qdisc show
qdisc noqueue 0: dev lo root refcnt 2
qdisc pfifo_fast 0: dev enp0s25 root refcnt 2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc noqueue 0: dev br0 root refcnt 2
I have this interface added to a bridge:
% brctl show
bridge name bridge id STP enabled interfaces
br0 8000.001999bf72bb no enp0s25
Why can't I delete pfifo_fast
from the root qdisc?
