This bug has been copied from bug #579774 and has been proposed
to be backported to 5.3 z-stream (EUS).
Technical note added. If any revisions are required, please edit the "Technical Notes" field
accordingly. All revisions will be proofread by the Engineering Content Services team.
When an SFQ (Stochastic Fair Queuing) qdisc that limited the queue size to two packets was added to a network interface (for example, via "tc qdisc add"), sending traffic through that interface resulted in a kernel crash. With this update, such a qdisc no longer results in a kernel crash when sending traffic.
