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 Signed-off-by: Eric Dumazet Signed-off-by: David S.
