So, how do we reliably calculate the minimum value for
buffer/burst/maxburts?
Trial & Error, not that I ever had much luck with TBF though...
From my experiments, the minimum seems to be either MTU plus a few bytes or
the result of rate/HZ, whichever is higher.
Both the buffers need to be at least MTU and if you shape on eth MTU+14.
You should set the limit buffer to the length of queue you want -
1*MTU(+14) is pretty useless for a limit but OK for burst.
I am not sure about tbf and Hz if it's like htb you need to set burst
big enough so its size * HZ can fill the link.
