I do not understand why they are failing. The del rules are exactly the same as the add rules, except they say del instead of add. I can clear the rules by deleting the root qdiscs on the interface, but that removes all rules for the entire interface, which is not the desired operation. Also, a quick test by hand shows that it is only from having a child class assigned to it that it becomes un-deletable. This works fine: wireless-r1 raddb # tc class add dev wivl4 parent 5:0 classid 5:56 hfsc ls m1 1536.0Kbit d 2000ms m2 256.00Kbit ul m2 1024Kbit wireless-r1 raddb # tc class del dev wivl4 parent 5:0 classid 5:56 hfsc ls m1 1536.0Kbit d 2000ms m2 256.00Kbit ul m2 1024Kbit This does not: wireless-r1 raddb # tc class add dev wivl4 parent 5:0 classid 5:56 hfsc ls m1 1536.0Kbit d 2000ms m2 256.00Kbit ul m2 1024Kbit wireless-r1 raddb # tc class add dev wivl4 parent 5:56 classid 5:57 hfsc sc umax 1500b dmax 30ms rate 80Kbit wireless-r1 raddb # tc class del dev wivl4 parent 5:56 classid 5:57 hfsc sc umax 1500b dmax 30ms rate 80Kbit wireless-r1 raddb # tc class del dev wivl4 parent 5:0 classid 5:56 hfsc ls m1 1536.0Kbit d 2000ms m2 256.00Kbit ul m2 1024Kbit RTNETLINK answers: Device or resource busy I have looked everywhere trying to figure this out.
