Ubuntu 14.04.1 LTS: ocorrências de regra de filtro tc não mostradas

Question

Tenha um Ubuntu 14.04.1 LTS. Não há estatísticas de ocorrências de regra na saída do comando tc filter show:

tc -s -d filtro mostra dev eth0

filter parent 1: protocol all pref 1 u32
filter parent 1: protocol all pref 1 u32 fh 800: ht divisor 1
filter parent 1: protocol all pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:11
  match 0afc0200/ffffff00 at 16
filter parent 1: protocol all pref 1 u32 fh 800::801 order 2049 key ht 800 bkt 0 flowid 1:11
  match 0afcc900/ffffff00 at 16
filter parent 1: protocol all pref 2 u32
filter parent 1: protocol all pref 2 u32 fh 801: ht divisor 1
filter parent 1: protocol all pref 2 u32 fh 801::800 order 2048 key ht 801 bkt 0 flowid 1:12
  match 00000000/00000000 at 16
filter parent 1: protocol all pref 2 u32 fh 801::801 order 2049 key ht 801 bkt 0 flowid 1:12

A mesma saída de comando no Debian:

filter parent 1: protocol all pref 1 u32
filter parent 1: protocol all pref 1 u32 fh 800: ht divisor 1
filter parent 1: protocol all pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:11  (rule hit 62382829 success 24954907)
  match 0afc0200/ffffff00 at 16 (success 24954907 )
filter parent 1: protocol all pref 1 u32 fh 800::801 order 2049 key ht 800 bkt 0 flowid 1:11  (rule hit 37427922 success 2200029)
  match 0afcc900/ffffff00 at 16 (success 2200029 )
filter parent 1: protocol all pref 2 u32
filter parent 1: protocol all pref 2 u32 fh 801: ht divisor 1
filter parent 1: protocol all pref 2 u32 fh 801::800 order 2048 key ht 801 bkt 0 flowid 1:12  (rule hit 35227893 success 35227893)
  match 00000000/00000000 at 16 (success 35227893 )
filter parent 1: protocol all pref 2 u32 fh 801::801 order 2049 key ht 801 bkt 0 flowid 1:12  (rule hit 0 success 0)

Como posso ativar essas estatísticas?
