[PKT_SCHED]: netetm: trap infinite loop hange on qlen underflow Due to bugs in netem (fixed by later patches), it is possible to get qdisc qlen to go negative. If this happens the CPU ends up spinning forever in qdisc_run(). So add a BUG_ON() to trap it. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S.
