<para>Specifies the credit per dequeue RR round, i.e. the amount of bytes a flow is allowed
to dequeue at once. When suffixed with K, M, or G, the specified size is parsed as Kilobytes,
Megabytes, or Gigabytes, respectively, to the base of 1024. Defaults to unset and kernel's

allowed to dequeue initially. When suffixed with K, M, or G, the specified size is parsed as
Kilobytes, Megabytes, or Gigabytes, respectively, to the base of 1024. Defaults to unset and
