Starting from linux-3.13, we can break the 32bit limitation of rates on HTB qdisc/classes. Prior limit was 34.359.738.360 bits per second. lpq83:~# tc -s qdisc show dev lo ; tc -s class show dev lo qdisc htb 1: root refcnt 2 r2q 2000 default 1 direct_packets_stat 0 direct_qlen 6000 Sent 6591936144493 bytes 149549182 pkt (dropped 0, overlimits 213757419 requeues 0) rate 39464Mbit 114938pps backlog 0b 15p requeues 0 class htb 1:1 root prio 0 rate 50000Mbit ceil 50000Mbit burst 200000b cburst 0b Sent 6591942184547 bytes 149549310 pkt (dropped 0, overlimits 0 requeues 0) rate 39464Mbit 114938pps backlog 0b 15p requeues 0 lended: 149549310 borrowed: 0 giants: 0 tokens: 336 ctokens: -164 Signed-off-by: Eric Dumazet <edumazet@google.com>
