net_sched: sch_sfq: add backlog info in sfq_dump_class_stats()
We currently return for each active SFQ slot the number of packets in
queue. We can also give number of bytes accounted for these packets.
tc -s class show dev ifb0
Before patch :
class sfq 11:3d9 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 0b 3p requeues 0
allot 1266
After patch :
class sfq 11:3e4 parent 11:
(dropped 0, overlimits 0 requeues 0)
backlog 4380b 3p requeues 0
allot 1212
