[Bloat] About Setting Bandwidth limit with or without ethernet overhead?

[Y]

I am sorry. Dave.

My actual speed with this setting , almost expected .
Around 90kbytes per second actual speed = 810kbit per second actual
setting speed * 48/53 considering atm connection. 
This settled speed doesn't include ethernet framing.

Maybe , 
Bandwidth = without ethernet overhead
tc-stab overhead = -14 
is correct.

Thank you .
