Dust Li dbb5cc35b9 net: sched: fix `tc -s class show` no bstats on class with nolock subqueues ... [ Upstream commit 14e54ab914 ] When a classful qdisc's child qdisc has set the flag TCQ_F_CPUSTATS (pfifo_fast for example), the child qdisc's cpu_bstats should be passed to gnet_stats_copy_basic(), but many classful qdisc didn't do that. As a result, `tc -s class show dev DEV` always return 0 for bytes and packets in this case. Pass the child qdisc's cpu_bstats to gnet_stats_copy_basic() to fix this issue. The qstats also has this problem, but it has been fixed in 5dd431b6b9 ("net: sched: introduce and use qstats read...") and bstats still remains buggy.
