ipfw pipe bursting, not working

[Ahmed Kamal]

Hi,

I am using pfsense (hope this is not frowned upon) to configure ipfw
limiting. I am finding that rate limiting is working great, however the
"burst" parameter does not seem to have any effect at all. I found this bug
open https://redmine.pfsense.org/issues/3933 .. Based on the milestone, I'm
not expecting a speedy fix.

I would like to help debug whats wrong, I am pasting below the output of
"ipfw pipe show" I am hoping a more experienced eye can spot a
misconfiguration .. Thanks for the help
