pkt_sched: Fix resource limiting in pfifo_fast
pfifo_fast_enqueue has this check:
if (skb_queue_len(list) < qdisc_dev(qdisc)->tx_queue_len) {
which allows each band to enqueue upto tx_queue_len skbs for a
total of 3*tx_queue_len skbs. I am not sure if this was the
intention of limiting in qdisc.
Patch compiled and 32 simultaneous netperf testing ran fine. Also:
# tc -s qdisc show dev eth2
qdisc pfifo_fast 0: root bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
