This was a meta-comment on the use case for doing this with mirred
action. Not necessarily about the patch itself.
I was actually curious where this happens in practice. The only thing
I can think of is your external logging box moved so you need to send
out another port. Is there any open source software that manages 'tc'
like this. If so I would like to read it.
So do you know of any?
